PMOS for OS/2.
Overview description of PMOS
PMOS is a large library of
Modula-2 modules, distributed in
source form. Its primary purpose is to make it easy to
write multitasking programs for real-time and/or embedded
applications. However it also contains a number of modules
of interest even if you don't want to write multitasking
code: screen windows and screen graphics modules, various
device drivers, and a variety of utility modules.
PMOS is free for non-profit use.
As distributed, PMOS is written for use on IBM-PC compatible
hardware; but large parts of it are portable.
To obtain the PMOS source code, fetch the file
(don't forget to set binary mode for ftp transfers), and
unzip into a disk directory of your choice.
After unzipping, you will find another README file among the
unzipped files. Read it for further installation information.
If you have trouble fetching from this site, look for PMOS
at one of the following places (but they won't necessarily have
the latest version). Remember that choosing a too-distant site
might give you painfully slow transfers.
Note that some of these were never intended to be general-purpose
ftp sites, so there are no guarantees about how long the copies
will stay there.

What's new in 2.2?
Version 2.2 was released on 23 March 1995. The main new features are
- Improved portability. It now works with TopSpeed version 1.17,
and parts of it now work with FST. (Sorry, I never quite finished the
- For TopSpeed version 3, memory models Small..XLarge are now all
supported. You can now do multitasking without having to use the
much-maligned MThread model.
- Improved graphics.
- Improved menus.
- Polyphonic music.
- Numerous minor improvements in many modules.
The following files are already part of the PMOS package, and
are provided for the benefit of those who don't want the entire
package. Don't bother fetching them if you already have PMOS.
- The PMOS preprocessor - you can fetch either the
zip file with full sources or the
documentation only. This is a preprocessor which allows you to
maintain multiple variants (e.g. versions for different compilers) of
