4  System requirements
**********************

The program runs on any computer using the (Atari-) TOS operating
system with 1Mb or more memory. The memory requirements for images
depends on the colour depth. The greater the colour depth the more
memory required. Using a True colour graphic card (24 or 32 bit)
gobbles up memory and you're likely to need considerably more than
1Mb.

CAB is resolution independent with two limitations: At 320x200 (ST-
low) not all of the dialogs fit entirely on screen, at 640x200 (ST-
Medium) the screen display is distorted (half height). Consequently we
recommend using CAB at resolutions of 640x400 (ST-high) or higher with
any number of colours, a multitasking environment (e.g MagiC, Geneva
etc) is also desirable.

Although not absolutely necessary the use of vector fonts via NVDI
v3.x or SpeedoGDOS is recommended. The system font or bitmap GDOS
fonts can however be used if required.



5  Installation
***************

*Attention:*

    Since v1.0 the program can no longer be installed as a desktop
    accessory.

    Configuration files from older versions of CAB (CAB.INF)
    cannot be used. Unfortunately you'll have to reset your
    settings manually.

    The format of the Hotlist file has also been altered but
    unless a file in the new format is available the old Hotlist
    file (CAB.HOT) is loaded. The new Hotlist file is called
    hotlist.html. As soon as the Hotlist has been saved in the new
    format the old file (CAB.HOT) can safely be deleted.

HTML files downloaded from WWW sites often include long filenames
which can easily result in duplication of filenames using the basic
TOS 8+3 character file system. It's well worth setting up a Minix hard
disk partition or other file system which supports long filenames to
handle HTML files.

The CAB distribution is supplied ready to run once unarchived onto
your working disk but you should still review the settings in the
Options menu and configure the options to suit your needs.



6  Navigating HTML Documents
****************************

Click on any underlined keyword to branch to the new page. Press the
[Undo] key to step to return to the previous page. Clicking on a link
using the right mouse button will display the address of the page it
links to.



7  Module for on-line Internet access
*************************************

To browse WWW pages on-line to the Internet a further module (CAB.OVL)
is needed. This module should be copied to the same directory as
CAB.APP. This file contains the additional routines needed to access
the Internet.

On Minix partitions the x-flag of the CAB.OVL file must be set
otherwise the modul can not be started.

I'm not able to test an Internet module but have built an interface
into CAB (HTML-Browser) to enable anyone capable of programming these
routines to create an on-line module. The description of this
interface is available on request and is available as commented C or
Pascal source. I'd like to hear from anyone who programs an on-line
module and would like a copy to distribute with CAB (HTML-Browser)...



8  Description of menu items
****************************


8.1  Open URL...
================

The *Open URL...* option in the *File* menu displays the URL dialog
containing any URL (Universal Resource Locator) addresses you have set
up to access the WWW.


8.2  Open local...
==================

The *Open local* option in the *File* menu calls the file selector which
can be used to open any HTML document from hard disk or CD-ROM.

Any file types can be selected. HTML, XBM and GIF files are normally
displayed by CAB (HTML-Browser) with other file types handled by
external programs. Refer to *External programs* for more details.

If a folder is selected the contents of the folder and sub directories
are displayed graphically as an HTML page and any files and folders
can be selected using the mouse!


8.3  Reload
===========

Reloads the HTML page again. This function is useful (in a
multitasking environment) for editing HTML pages in an editor with CAB
running parallel to display the pages.

If the page originated from the WWW using *Reload* will fetch the page
from the WWW again -even if a copy is available in the cache.


8.4  Print
==========

If GDOS is available the document in the topped window can be output
as text. Bitmap fonts require matching screen and printer fonts
whereas vector fonts under NVDI 3.x or SpeedoGDOS are automatically
scaled as required.

In the dialog the margins can be set. These are in addition to any
offsets or margins attributable to either the printer or GDOS driver.
A popdown menu offers selection between any installed GDOS driver
including, so long as a suitable GDOS driver is available, GEM
Metafile (*.GEM) or bit image (*.IMG).

Successful image output relies on the GDOS printer driver supporting a
particular VDI function which may or may not be implemented in the
active driver. We recommend you try printing with images turned on and
if it doesn't work simply turn the option off for subsequent output.
If you're using a dot matrix printer activate the option to lighten
images otherwise the printed output is likely to be too dark.


8.5  New window
===============

Opens a new window displaying the contents of the previously topped
window.


8.6  Close window
=================

Closes the window.


8.7  View source
================

Displays the source text of the displayed HTML document. Also refer to
the *External programs* menu option.


8.8  Quit
=========

Exits the program.


8.9  Home page
==============

This menu option displays the home page, if available.

CAB tries to load the home page directly. Anyone who understands HTML
syntax can easily set any page as the home page and create a page to
reference other HTML documents. The file used as the home page can be
set in the *General options* dialog.


8.10  Back
==========

Displays the previous document.


8.11  Find keyword
==================

This allows the user to perform a search for keywords in HTML files,
and can optionally be case sensitive. The search can be conducted over
one of the following ranges of documents:

  1. Current document only. The text is searched for in the current
     document (the top window). If the text is found the window is
     scrolled so the text is displayed at the top of the window.

  2. Local HTML Documents. The text is searched for in all local HTML
     documents contained in the paths specified in the *Paths* dialog
     box (and their subdirectories). The files that contain the text
     is made into a list of links in an HTML file called result.html.

     At the moment the HTML files searched by method two are searched
     purely as text, so hidden text such as comments, HTML commands,
     links and so are also found. Processing the files to ignore
     hidden text would be very time costly. This also means that
     special characters such as accents and so on which are written
     into HTML code using commands like &auml; are not found. This
     shortcoming may be addressed in a future version.

     Another tip: If you're searching for something which is often
     used in HTML code as a command or URL-address placing a space
     before it may make it less likely to turn up in commands or URL
     addresses..

     For example: Searching for the text 'WWW' often matches
     subdirectories and addresses for pages in the form
     '.../WWW/foo.html...'. Placing a space before it in the search
     string, ' WWW' removes these occurences resulting in a better
     targetted search. These don't apply to methods 1) and 3)!

  3. In the c't-CDROM Database. This option is only useful for people
     with the c't-CDROM (the 1994 (or 92/93) c't magazines in HTML
     format)!

     In this case the HTML files themselves aren't searched, but the
     index file on the CD is accessed instead. So that HTML-Browser
     knows where the files for this CD are kept are, you need to fill
     in the appropriate section of the *Paths* dialog box - the HTML
     documents (in \HTML which also contains the file DEFAULT.HTML)
     and the index database (\UNIX\CT94.DAT or \UNIX\CT9293.DAT). As
     in the previous method, matching documents are made into an HTML
     document called results.html which is then opened.


8.12  Hotlist
=============

The hotlist is a list of your most used HTML documents. This list
enables you to get quickly to you favourite pages, without having to
navigate through a long series of pages to get there.

The hotlist is divided into themed areas. Using the popup at the top
of the dialog it's easy to switch between different themes.

*The 'Theme...' popup:*

 *Change theme:* Changes the name of the current theme area. The
     /Miscellaneous/ area cannot be renamed.

 *New theme:* Creates a new theme area.

 *Delete theme:* Delete the current theme area. The /Miscellaneous/ area
     cannot be deleted. All remaining entries in a deleted theme area
     are moved to the /Miscellaneous/ theme area.

*The 'New theme...' popup:*

    Using this option a selected entry can be moved to another
    theme area.

*The 'Document...' popup:*

 *Delete entry:* Deletes the selected entry.

 *Change entry:* Changes the selected entry. Annotations to the page can
     also be made.

 *Open document:* Opens a document.

 *Add current doc:* Copies the current document to the Hotlist.

Double clicking on an entry opens the document.

The Hotlist is saved to disk as a normal HTML document which provides
an easy way for anyone not familiar with HTML syntax to create their
own home page.


8.13  Document -> Hotlist
=========================

The current document is inserted in the Hotlist provided it's not
already listed. It will be filed away in the /Miscellaneous/ theme area.


8.14  General options
=====================

 *Home page:* After launching CAB or by selecting the *Home page* menu
     entry the specified HTML file will be displayed. Often it's
     useful to create a home page containing references to frequently
     used HTML pages. By default CAB attempts to load home.html as the
     home page although any page can be set to be the home page
     -simply enter the URL address. If the file is located in the
     specified start directory for CAB.APP you can select the *Start
     folder* button and using the *Search* button select the desired file
     using the file selector.

 *Popup menus:* CAB provides a row of popup menus to relieve the tedium
     of navigating through HTML pages. Basic principle:

        ù Left click on a reference to branch to the corresponding
          page.

        ù Right click on a reference to display the destination of the
          reference.

        ù Click on the window background (not on a reference) to
          display further popup menus.

     You can set which menu will be displayed using the left and right
     mouse clicks (with and without holding down the [Shift] key). The
     following popup menus are available:

      *History:* Lists the previously displayed documents.

      *References:* Lists the references in the current document.

      *Menu:* Lists some menu items.

 *Miscellaneous:* During loading, formatting and data transfer from the
     Internet CAB displays a series of reports in a windowed dialog
     (if the option *Dialog for Status messages* is active) otherwise
     the window info line is used instead. The display in the window
     info line has a couple of disadvantages. First a window may not
     be open to display the information and secondly the dialog
     displays the information more clearly. On the other hand using
     the window info line allows a document in the window can be read
     and scrolled while the text is still being formatted.

     The *load index.html automatically* only has an affect on local
     references (ie to files/directories on your drive) If the
     reference points to a directory on a drive the contents will be
     displayed unless a file index.html exists in which case this is
     loaded instead. On use for index.html is to set up a page
     containing an index of all your favourite documents.


8.15  Display
=============

In this dialog you can configure various display options for HTML
documents.

 *Colours:* This section allows you to configure the display colours,
     for the foreground text, the background colour and link colour.
     If you're using less than 16 colours, the window background will
     always be white regardless of the settings here. In 16 colour
     mode, only the first nine colours should be used as the last 7
     may be changed for pictures etc. In more than 16 colours, any of
     the first 16 can be used as they will not be changed.

     Some HTML documents include information about which colours
     should be used for text, references and the window background.
     The option *Use guidelines in document* tells CAB to use this
     information (if available).

 *Links:* Links can be displayed in underlined and/or bold text (this is
     important for monochrome systems which can't distinguish links by
     colour).

 *Images:* Controls image display.

      *Don't show* Prevents images being loaded and displayed which
          speeds up page loading.

      *Monochrome* Images are displayed in monochrome using dithering.
          It's the quickest method but this obviously the quality
          suffers.

      *Greyscale* Images are displayed as greyscales. Higher quality
          display at the expense of speed.

      *Colour* Images are displayed in colour depending on the hardware
          available:

             ù 4-8 bitplanes (16-256 colours). Images are dithered if
               the number of colours available is less than the number
               of colours contained in the image. In 16 colour modes
               greyscale display is often more suitable.

             ù 15/16 bit Highcolor (32768/65536 colours) eg Falcon
               Truecolor mode

             ù 24 or 32 bit Truecolor (16.7 million colours)

      *Text instead of images* The HTML language provides for text only
          systems by allowing images to be accompanied by some text
          which is displayed instead of the image. This enables WWW
          Browsers which cannot display images to display text output
          instead. If this option is active (crossed) only images for
          which no alternative text is available are displayed as
          images.

 *Text width:* Text can either be formatted at a fixed width or
     justified to fit the window width. Text justified to fit the
     window width looks better but takes longer to display as the text
     must be reformatted.


8.16  Font selection
====================

Wherever possible CAB (HTML-Browser) uses different fonts and point
sizes to display HTML files. Optimal output quality is provided using
vector fonts for which you'll need to install either NVDI v3.x or
SpeedoGDOS. Normal bitmap fonts can be used but they're not nearly as
nice.

Next you need to tell CAB (HTML-Browser) which (GDOS) fonts to use for
each corresponding style in an HTML document. Vector fonts as provided
by SpeedoGDOS or NVDI 3.x are recommended. You must specify three
fonts (sans-serif, serif and monospaced) in four different styles
(normal, bold, italic and bold and italic) making twelve selections
altogether.

For the bold and italic settings you should use a 'real' bold or
italic font wherever possible. If you don't have one available you'll
have to simulate these text effects using the corresponding buttons
adjacent to the font selection popup. If you're using vector fonts
then use the appropriate font from the font family, if available.

Some commands such as <PRE>...</PRE>, <FORM>...</FORM> etc will cause
display format problems with /proportional/ fonts. To avoid these
problems only use *non-proportional* fonts for *preformatted* text.

The supplied INF file has the following presets (for NVDI 3.x):

 *Headings:* Swiss 721 (normal, bold, italic, bold+italic)

 *Normal text:* Dutch 801 (normal, bold, italic, bold+italic)

 *Formatted:* Letter Gothic 12 Pitch (normal, bold, italic, bold+italic)

If you don't like or haven't got these fonts, you'll have to select
alternatives.

The size of the body text can also be altered. Don't make this too
large or too small! Somewhere between 10 and 13 point is sensible (I
use 12 point).

If you haven't got access to vector fonts (i.e. you don't own a copy
of NVDI 3.x or SpeedoGDOS) then the point size won't change, but the
text can still be viewed using the system font, usually 10 point.


8.17  External viewers
======================

If a link in an HTML document points to a file which is not in HTML
format, an external viewer can be called. These programs can be called
in one of two ways and are configurable via the *External programs...*
dialog via the *Options* menu.

Individual file types can be assigned to different programs. File
extensions are entered into the *Files* field. Several extensions can be
entered using a comma to separate each entry.

Programs are selected by clicking on the selection box to the right of
the *Files* field which displays the file selector to select the desired
viewer.

Finally each entry includes a *Supports VA_START* checkbox which should
be crossed if the viewer understands the VA_START message so CAB can
send a VA_START message to the viewer so the file can be viewed with
re-launching the viewer.

The *Default* program (*.*) is called to display any files for which no
program has been assigned.

If one of more extensions have been defined without a program assigned
CAB attempts to display the file. This is only sensible for *.gif,
*.xbm, *.htm and ASCII files (for example: *.txt, *.doc, *.c, *.pas,
*.tex etc...) for which CAB (HTML-Browser) includes built-in display
routines. When any non ASCII format file is encountered CAB displays
the file selector using which a copy of the file to be saved to any
desired location.

The current HTML page can be displayed as source text by selecting an
application in the *Source* entry. This application is called via the
menu entry *View source...*. If no application has been assigned the
*Default* program is called instead.

Double clicking on the *program path* boxes opens a further dialog with
an option to clear the current path.

Some suggested external programs:

 *.text,txt:      ST-Guide, 1st-Guide (or none, then HTML.APP is used)

 *.mpeg,mpg,mpe:  1st-Guide (on a Falcon under Single TOS the fast DSP
                  MPEG player is recommeded)

 *.jpeg,jpg,jpe:  1st-Guide, GEMview

 *.tiff,tif:      GEMview, Imagecopy

 *.gif,xbm:       GEMview, Imagecopy (or none, then HTML.APP is used)

 *.dvi:           DVI display included in TeX archives

 *.* (Default):   GEMview (or other program which handles as many
                  formats as possible)

 *.html,htm:      ST-Guide, 1st-Guide, (or and editor so the HTML
                  source can be edited)


8.18  Paths...
==============

If you have a copy of the c't ROM '94 (or 92/93) (CD containing the
contents of the German magazine c't) then set the path for the field
c't CDROM.

In the *HTML folder* field set the directory which contains the file
DEFAULT.HTM on the CD (eg ?:\HTML\, where ? is replaced with the drive
letter of your CD-ROM drive). In the *Database* field set the path to
the contents of the CD (?:\UNIX\CT94.DAT (or ?:\UNIX\CT9293.DAT),
again ? is the CD-ROM drive letter).

If you want to use CAB online to an Internet WWW site you should set
the *Cache folder* where all files downloaded from the Internet can be
stored. Ideally this folder should be on a Minix hard disk partition,
or other file system which supports long filenames to handle HTML
files because HTML files downloaded from WWW sites often include long
filenames which can easily result in duplication of filenames using
the basic TOS 8+3 character file system -and make sure the partition
has plenty of room!

In *HTML folders* you can enter the paths CAB (HTML-Browser) looks to
find HTML files.

HTML files contain absolute local paths (eg /path/file.html) which can
soon turn the root directory of your partition into choas. The HTML
folders help avoid this by telling HTML-Browser to look for HTML files
in the folders specified.

Here's an example:

 *Entered HTML folders:*

        ù F:\HTML.DOC\

        ù G:\VARIOUS\

 *Current drive:* F:\

 *Path in HTML file:*

        ù /example/text/index.html

 *Where CAB looks:*

       1. F:\example\text\index.html

       2. F:\HTML.DOC\example\text\index.html

       3. G:\VARIOUS\example\text\index.html

Double clicking on the *program path* boxes opens a further dialog with
an option to clear the current path.


8.19  Cache
===========

CAB (HTML-Browser) uses two caches to maximise the display of files.

The *Image cache* is used to avoid repeated unpacking and dithering
which both take a great deal of processing time. Images no longer
displayed are held in memory (RAM) in case they are needed again.
Naturally this takes memory so the maximum size of the cache can be
set in the *Maximum size* field. If the cache becomes full the least
used image is purged from the cache to free up more space. Using the
*Keep free* option it's also possible to set the minimim amount of
memory free for other applications. The cache can also be manually
purged using the *Free cache* button which can be useful to quickly free
up more memory for another application under a multitasking OS. The
cache remains empty until further images are displayed in CAB (HTML-
Browser).

*Attention*

    The actual memory consumption for the Cache can be higher than
    entered in the dialog.

The *Internet Cache* is used to store files downloaded from the Internet
on your disk to avoid repeatedly downloading the same files from the
Internet if they're viewed more than once. See also *Paths*

The *Maximum size* and *Keep free* options limit the amount of disk space
used by the cache and CAB (HTML-Browser) will purge the oldest files
from the cache to maintain the cache within the defined limits.

If the *Delete after 'quit'* option is active (crossed) the files in the
cache will be deleted on exiting CAB (HTML-Browser). Naturally unless
disk space is limited or you're sure you'll never need the files again
it's best to keep the files.

The *Free cache* button is for emergency use in case you need extra disk
space fast! Only files placed in the the cache directory placed there
by CAB (HTML-Browser) will be deleted.

*************

Each CAB window contains a button bar which provides an easy way to
access some of the more important functions:

 *Back* Displays the previous document

 *Home* Displays the home page

 *URL* Select a document from a URL address

 *File* Select a file using the file selector

 *Source* Displays the source text of the currently displayed document

 *New* Reloads the current document again

 *Hotlist* Displays the hotlist dialog

If a 'sad' smiley appears to the right of the buttons it means the
displayed document is faulty in some way. Click on to the smiley to
display detailed error information. This is a particularly useful
option for anyone using CAB to author HTML pages. Only errors which
CAB can determine without wasting disk space or processing time will
be reported.

Faulty documents are not neccessarily displayed incorrectly in CAB but
may well exhibit display problems in other browsers (e.g. Mosaic,
Netscape, WebExplorer etc) may not display the document as you
intended.

12  History
***********

========================

   ù Reduced memory requirements

   ù MTOS Drag&Drop (ARGS) supported

   ù External programs will now run under single TOS

   ù Error reports are now more descriptive

   ù Bugfix: when running as an accessory no longer tries to invert
     (non-existant) menu items

   ù The .INF file is now found even if HTML is not started in it own
     directory

   ù Is now a lot more tolerant of buggy HTML file syntax.

   ù home.html is now loaded on startup if possible

   ù Hotlist

   ù Configuration of window and text colours etc.

   ù Search (including searching c't CDROM)

   ù In-line images can be displayed as greyscales


12.3  V0.93ž (07.06.1995)
=========================

   ù Preparation for on-line operation implemented (although not
     activated in this version)

   ù Bugfix: Problem with line spacing fixed

   ù Bugfix: Endless loop with defective gifs fixed

   ù Bugfix: fclose() for Hotlist was forgotton :-(

   ù A few other minor bugfixes


12.4  V0.94ž (07.07.1995)
=========================

   ù Bugfix: Deleting the last Hotlist entry caused a crash :-(

   ù Bugfix: CR/LF inside tags led to problems

   ù Bugfix: Last word in an HTML file gobbled

   ù Documents access using absolute path information, including
     directories listed in the 'Paths...' dialog

   ù Contents of a drive can be displayed as an HTML document
     (including launching programs and viewing files)!

   ù Support for the special Netscape <CENTER> tags


12.5  V0.95ž (04.08.1995)
=========================

   ù Inline colour images

   ù Configurable image cache (in RAM)

   ù Configurable WWW cache (on disk)

   ù Option to automatically format text to the window width

   ù ASCII, xbm and gif files can now be viewed directly in HTML-
     Browser. Calling external programs is no longer required (but
     naturally still available as an option)

   ù Interface for 'Internet module' implemented Using a suitable
     module HTML-Browser could be used to display WWW pages on-line to
     the Internet, naturally you'd need an Internet account to do
     this!

   ù Support for xbm images


12.6  V0.96ž (22.08.1995)
=========================

   ù Lots of minor bugfixes


12.7  V0.98ž (03.10.1995)
=========================

   ù In colour resolutions with fewer than 16 colours the colour
     palette is no longer altered

   ù Zero length files should no longer cause problems

   ù The program is now called:
     CAB - The Taxi to the information highway!
     CAB = Crystal Atari Browser


12.8  V1.0 (01.11.1995)
=======================

   ù Minor adjustments to accomodate the 3D look under Geneva release
     4 (unfortunately Geneva is not entirely MultiTOS compatible)

   ù Multiple open windows may be opened

   ù Each window may individually configured with its own colour and
     font

   ù Support for the following Netscape tags (commands):

        - <FONT SIZE=[+|-]n> </FONT>

        - <BASEFONT SIZE=n>

        - <CENTER> </CENTER>

        - <NOBR> </NOBR>

        - <BODY BACKGROUND=url BGCOLOR=#rrggbb TEXT=#rrggbb
          LINK=#rrggbb>

   ù Support for the <FORM>-area (forms)

   ù Tables (<TABLE>...</TABLE>) are supported.

   ù The Hotlist dialog has been extended to accomodate themes. Each
     entry can be optionally be annotated

   ù Cache management has been changed. Files are no longer saved in
     the cache using their original names which should avoid problems
     long filenames may have caused on standard TOS 8+3 character file
     systems

   ù History popup implemented

   ù Popup showing all links in a page

   ù <IMG ...> with the attribute ALIGN=LEFT or ALIGN=RIGHT now
     functions correctly.

   ù Font sizes in the <Hn> </Hn>-areas changed (in line with the
     method used by Netscape and Mosaic)

   ù Search now works correctly with the 92/93 c't ROM database

   ù New: Button bar in the window provides convienient access to most
     important functions.
     If a 'sad' smiley appears to the right of the button bar the
     displayed document does not conform to HTML specification. CAB
     will nevertheless try to display the document which may well look
     fine. On the other hand a 'happy' smiley does not indicate a
     perfect document because CAB does not waste resources analysing
     documents in-depth.

   ù Right aligned format (ALIGN=RIGHT) is now supported.

   ù Numerous minor bugfixes ;-)


12.9  V1.0a (12.12.1995)
========================

   ù Bugfix: Where available the transparent colour of background
     images is evaluated.

   ù Bugfix: In larger than 32Kb HTML files where tables are included
     after the first 32Kb garbage (maybe even crashes) was likely.

   ù The cursor keys can be used to scroll the window. If a form is
     depicted and the cursor is postioned in an input field the cursor
     keys can be used to navigate the form.

   ù Bugfix: Inside <PLAINTEXT> empty lines are no longer ignored.

   ù Bugfix: Under old TOS versions hard drive directories were not
     correctly evaluated.

   ù Bugfix: Under old TOS versions there were sometimes problems if a
     window title was set straight after opening a window.


12.10  V1.1a (01.04.1996)
=========================

   ù When CAB is used offline (i.e. CAB.OVL is not installed) all
     links are sought after locally. For example an http address
     http://host/path/file would be handled as //localhost/path/file.

   ù When selecting the c't CD database it's now possible to use
     wildcards. For example 'K:\HTML\CT*.DAT' would find all the
     database files on all c't CDs.

   ù The closer icon now closes the window (previously this displayed
     the previous page). The previous page can still easily be
     accessed using the 'Back' button.

   ù In 640x200 (ST medium) resolution images are scaled to half
     height to maintain the correct aspect ratio (proportions).

   ù Holding down the [Shift] key when selecting a link displays the
     new page in its own window. Similarly holding down the [Shift]
     key when selecting 'OK' in the 'Open local', 'Open URL' and
     'Hotlist' dialogs displays the new page in a separate window.

   ù CAB now displays the source code itself if no suitable external
     application has been installed.

   ù CAB has been extended to understand the following Netscape
     extensions:

        - Using the <HR> tag the WIDTH=, SIZE=, NOSHADE and ALIGN=
          attributes are evaluated.

        - Using <TD> and <TH> the WIDTH= and HEIGHT= attributes are
          evaluated.

        - Client Side Image Maps are currently partially implemented:
          <MAP NAME=name> <AREA SHAPE=rect COORDS="x1,y1,x2,y2"
          HREF=url> </MAP>

   ù Minor optimisation to handle certain boxed tables built-in. In
     principal tables should be repeatedly calculated depending on the
     width of the window and consequently such tables are processor
     intensive.
     Example: The (early 1996) FOCUS pages (www.focus.de) possess a
     boxed table with seven nested levels and these take a ridiculous
     time to calculate (e.g longer than five minutes for some pages!).
     Of the seven levels only two are used sensibly (the rest consist
     of cells containing nothing other than other cells (OK it may be
     legal but it's stupid!)). CAB calculates such tables as a single
     cell (i.e. column) which results in substantially faster
     calculation -although this still isn't exactly rapid it's an
     improvement.

   ù Any filetype which cannot be displayed by CAB itself and for
     which no application has been installed (as defined by the file
     extension) can optionally be copied to any desired folder.

   ù GDOS printing now possible. Currently only monochrome images can
     be output. Output via other GDOS drivers also possible, e.g.
     Metafile, IMG etc.

   ù The Hotlist dialog can now be completely keyboard controlled if
     desired.

   ù The Clipboard, Cut [Control]+X, Copy [Control]+C and Paste
     [Control]+V commands are supported in all dialog editable fields.

   ù The Clipboard commands are also available in document editable
     fields.

   ù The window position is now saved using the 'Save options' entry
     in the 'Options' menu.

   ù Support for new (HTML3) commands:

        - <BIG>, </BIG> large text

        - <SMALL>, </SMALL> small text

        - <SUP>, </SUP> Superscript

        - <SUB>, </SUB> Subscript

        - <Q>, </Q>, <LANG>, </LANG>

   ù Hotlist entries can now be completely manually created.

   ù Bugfix: HTML files with exceptionaly long comments at the start
     which didn't have use the .HTM file extender (or .html on systems
     with long filename support) were displayed as ASCII.

   ù Bugfix: Tables with large numbers of lines and/or columns caused
     problems.

   ù Even more tolerance built-in to accomodate HTML authors who
     invent astonishingly convoluted HTML tags -even when a simple
     HTML command already exists :-\


12.11  V1.2 (10.04.1996)
========================

   ù Bugfix: When memory gets short CAB will free up less urgently
     required memory (e.g. images in the cache RAM). Thanks to an
     incorrect calculation this could lead to an endless loop.

   ù Print in colour is now also possible (so long as your GDOS
     printer driver supports this).

   ù The absolute size in pixels (with tables or <HR>) are now
     converted to the existing printer resolution on printing.

   ù OLGA protocol: CAB is a OLGA client

   ù First attempt at supporting JPEG images, the file CAB_JPEG.OVL
     takes care of JPEG images and should reside in the CAB directory.
     Note: CAB.OVL is still required for on-line browsing, do not
     rename either file!


12.12  V1.2a (16.04.1996)
=========================

   ù Bugfix: If CAB runs short of memory it tries to release more
     memory (e.g. by deleting images in the image cache). Thanks to a
     faulty calculation of the available free value CAB could get
     stuck in an endless loop.


12.13  V1.2b (19.04.1996)
=========================

   ù The printer margin entries were not evaluated correctly, if the
     entries were 3-stellig?.

   ù Bugfix: CAB tries to format tables even if the <tr> tag is
     missing so long as the </tr> tag is available. Due to a bug in
     CAB this led to problems with boxed tables. It should now
     function again.

   ù Colour printing with NVDI4 should now function correctly. !Item
     Bugfix: If the 'Use document setting' option (concerning the text
     and background colours was not selected no background image was
     displayed. Both settings are now independent of each other.


12.14  V1.3 (20.05.1996)
========================

   ù New JPEG module from Dieter Fiebelkorn

   ù Mail support (mailto:user@address)

   ù Proxy and SMTP-Server can be set directly from CAB (not
     applicable for local (offline) operation)

   ù A few more small bugfixes removed

   ù Unrecognised extensions ignored. For example JavaScript
     (<SCRIPT>...</SCRIPT>) is ignored and no longer displayed as HMTL
     text.

   ù 'Slide shows' via <meta http-equiv="Refresh" content="5;
     url=xyz"> now supported.

   ù <FONT> tag now supports colour (<FONT COLOR=...>)

   ù Colours in tables are now supported: BGCOLOR= for tables and/or
     cell background BORDERCOLOR=, BORDERCOLORLIGHT= and
     BORDERCOLORDARK= for the table edges

   ù The most important colour can now also be assigned by name as
     well as a hex number. For example COLOR=White instead of
     COLOR=#FFFFFF

   ù References can be followed during text formatting (the mouse is
     still not evaluated during image loading). Formatting is
     abandoned and the desired document loaded instead.


12.15  V1.4 (19.09.1996)
========================

   ù Using NVDI 4 for printed output requires a lot less memory
     because NVDI 4 is now given the responsibility to scale images.
     In particular the TrueColor, i.e. halftone printer driver (32
     bit/pixel). Unfortunately other GDOS software or replacements do
     not offer this feature -use NVDI!

   ù CAB now supports the same text colour descriptions as Netscape
     and MS Explorer.

   ù Stop button added so text formatting can be aborted using the
     mouse (corresponds to pressing the [ESC] key).

   ù During image conversion (dithering) CAB now notices AES events.
     This means it is possible to scroll documents, select links and
     break off formatting during image conversion.

   ù Bugfix: In 640x200 (ST-Medium) resolution the mouse co-ordinates
     for image maps where not scaled, now fixed.

   ù Source text is now displayed with all HTML tags and comments
     highlighted (HTML tags blue and comments red).

   ù The NetScape 'Frames' extension deviates considerably from the
     philosophy and practise of HTML. Normally WWW browsers can ignore
     any HTML tag it can't display without losing the underlying
     information in the file. Unfortunately this is not true for
     NetScape 'Frames' so browsers which do not support 'Frames'
     effectively lose information!
     CAB still doesn't support NetScape 'Frames' but now displays a
     list of all documents in a frame which provides access to the
     frame content.

   ù The external files and modules loaded by CAB can optionally be
     stored in a MODULES folder located inside the CAB folder or left
     in the same folder as CAB.APP. The following files are affected:

        - CAB_JPEG.OVL (this file may also be called JPEG.OVL)

        - CAB.INF

        - CAB.OVL

        - CACHE_ED.PRG and CACHE_ED.PRG (program to manage the WWW
          caches)

        - HOTLIST.HTML

   ù Images, with the WIDTH= and HEIGHT= attributes set are loaded
     after the text has been formatted. This means text is displayed
     faster. Images without the WIDTH= and HEIGHT= attributes have to
     be downloaded and displayed immediately because there is no way
     CAB (or any other browser) can know how large the image is.

   ù Bugfix: CAB could not load long filenames containing space
     characters passed via VA_START or Drag&Drop, this now functions
     again.

   ù New tags:

        - <DIV> </DIV>

        - <IMAGE> (another Netscape tag, identical to <IMG>)

   ù 'about:'-Protocol

   ù The WWW cache structure has been re-organised. Files are now
     stored in sub directories. This should avoid overfull directories
     and minimise the time taken to load/save files. On attempting to
     open an old format cache CAB automatically updates the file
     structure - this may take some time (but it is a once-only
     occurence).

   ù CAB-Protocol: Some AES messages to call various CAB functions
     from external programs has been implemented. A 'BROWSER'
     environmental variable should be defined containing the complete
     path to CAB. Programs requiring access to CAB functions can use
     this variable variable to locate/open CAB.

   ù In tables ALIGN=LEFT and ALIGN=RIGHT are evaluated.


12.16  V1.4a (01.10.1996)
=========================

   ù Bugfix: Some colours were not correctly depicted on printing via
     a TrueColor printer driver.


12.17  V1.5 (20.10.1996)
========================

   ù Bugfix: CAB mistakenly used the global colour palette for GIF
     files which include local colour palettes.

   ù Support for animated GIFs. Animations can be halted at any time
     using the Stop button.

   ù GIF animations can be turned off the in 'Options/Display'. This
     saves both memory and system resources, because only the first
     frame of an animated GIF is decoded and dithered. Images already
     in the cache remain intact and are displayed as still images if
     the GIF animations option is turned off.

   ù CAB now displays the destination of any link in the window Info
     line under the mouse pointer - which changes to a pointing hand.
     It is now no longer necessary to right click to reveal the
     destination.

   ù Bugfix: If a new cache folder was selected but no CACHE.CAB file
     had been created CAB did not always initialise the cache folder
     correctly.

   ù Bugfix: The last element in a list inside <CENTER> tags was not
     displayed correctly.

   ù Newer versions of CAB.OVL install themselves even if STiK is not
     on-line. This resulted in 'Network down' messages when STiK was
     off-line. CAB.OVL is now only called if STiK reports 'On-line'
     status.

   ù New dialog 'Options/Internet programs'. Here different programs
     for the various Internet protocols can be installed. In the case
     a URL calls one of these protocols the corresponding program will
     be called (on condition the program accepts a URL as a
     parameter). All protocols (still) not supported in CAB.OVL and
     for which suitable programs exist can now be used via CAB.
     Entries in this dialog take precedence over CAB.OVL.

   ù New 'Binary file' entry added to the 'Options/External programs'
     dialog. File extenders to be handled as binary files can be
     entered. Binary files for which no application has been installed
     can, via the file selector, be copied anyway to disk and CAB will
     not attempt to display them. This entry only applies to non-
     readable ASCII file formats including uuencoded files, Mac BinHex
     files etc. Such filetypes should be entered into the dialog. CAB
     automatically recognises 'real' binary files so these should not
     be entered here.

   ù The icons in the button bar can be toggled on/off by clicking on
     the small triangle to the right of the Stop button. Turning off
     the icons conserves display space.
