following information I am grateful to Richard Steiner, who cleared up
some of my confusion over the various versions floating around:
of 4OS2 has indeed been shelved by JP Software, but thanks to their
generosity (and release of the source code) there are still improvements
being made by third parties.
The source for
4OS2 3.04 was given by Rex Conn to Michal Necasek at SciTech Software
(makers of SciTech Display Doctor for DOS and the well known SNAP Graphics
drivers for OS/2 & Linux), and Michal has released a number of versions
containing minor box fixes to the OS/2 community.
versions have been numbered 3.04B through 3.04G (the last release just
made on 30 July 2005), and the only help file contains all of the changes
in the "What's New" section.
There was no SciTech version 3.04A, just B/C/D/E/F and G.
The last three versions are available here on the SciTech web site:
page leads to their ftp site.
The source for
4OS2 3.04B is available on the Hobbes FTP site. This source
compiles using the freeware
OpenWatcom compiler for OS/2, which is quite
Michal Necasek's and Steven Levine's 3.04H, Open Source
05-09] is posted at Open Watcom:
Difference from 3.04G, SciTech Edition:
- Fixed shift /1 crashes
- Fixed spurious REXX error reports
To make things a
little more complicated, another OS/2 programmer and long-time 4OS2
enthusiast (Doug Lindquist) found the 4OS2 source files on Hobbes and
decided to make some changes and minor enhancements of his own before
SciTech's (Michal's) involvement was very well known in the OS/2
were numbered starting at 4.00A (mainly due to some larger changes he had
made), but associated problems and conversations with Michal on
comp.os.os2.apps has resulted in his version being discontinued in favour
of a unified version from SciTech. His versions were 4.00A, 4.01A, and
Hope that helps
clear some things up regarding 4OS2 and the nature of the various versions
that are floating around.
