Version 4.0 -- November 18, 1991
Version 4.0 is a major new release and many parts of 4DOS have
changed. The list below summarizes these changes for version 3.0
through 3.03 users; users who are new to 4DOS with version 4.0 can
skip this information.
4DOS is now a single file, 4DOS.COM. The old structure of separate
4DOS.COM and 4DOS88.EXE / 4DOS286.EXE files has been eliminated.
There is a wide variety of new startup options for 4DOS, ranging
from the simple to the highly technical. Most of the startup
switches that used to go on the SHELL= line in CONFIG.SYS or in the
4DSHELL environment variable have been eliminated, and 4DOS config-
uration is now controlled through the new 4DOS.INI file, for both
primary and secondary shells. Those switches which still work for
DOS compatibility reasons (such as /E: for environment size) can
also be set through 4DOS.INI.
Swapping is now controlled by the Swapping directive in 4DOS.INI.
You can use this directive to set up any sequence of swapping at-
tempts you like (for example, you can tell 4DOS to try EMS, then
your RAM disk, then XMS, then the hard disk). If no Swapping di-
rective is used the default is to try EMS, then XMS, then the root
directory of the boot drive if it is drive C: or higher. 4DOS will
no longer attempt to swap to drive A: or B: by default (though you
can tell it to if you want to). If all of these methods fail, 4DOS
will load resident.
For BBS operators, the /F startup switch (or the CritFail directive
in 4DOS.INI) generates an automatic "fail" response to all critical
errors.
The PATH search is now faster by 50 - 100% depending on where the
file is found in the path.
Secondary shells now require only about 1.7K of resident space
(down from about 2.8K in version 3.03). The primary shell require-
ment is still 3K or less under most circumstances.
Description file processing has been sped up substantially, and
should generate much less network traffic than before.
Directory displays in DIR and SELECT can now be colorized based on
file extension or attributes. See "COLORDIR".
Wildcards have been enhanced so that you can specify lists or rang-
es of characters to include or exclude. For example [abf-h]*.*
means all files whose names begin with a, b, f, g, or h. See
"Wildcards".
4DOS now performs variable expansion on the prompt string, so any
environment variable, internal variable, or variable function can
be put into the prompt and displayed.
When 4DOS exits from a shell it looks for and executes a 4EXIT.BAT
or 4EXIT.BTM file (like the 4START file). This can be used to save
history or perform other actions.
All upper case conversions (SETDOS /C1, DIR /C, @UPPER, etc.) now
support international characters.
The help system has been extensively revised. It now supports line
by line scrolling, and scrolling and paging with the mouse follow
industry standard conventions. The mouse can be used more easily
to perform most help navigation functions.
and much much more.
