It *only* runs under MS-DOS (or DR-DOS, if you prefer), but it comes
with an OS/2 utility allowing it to start native OS/2 programs. This
utility is OS2EXECD.EXE written by Eberhard Mattes. To use it, start
os2execd.exe from an OS/2 command prompt; it will open a window and
wait for messages. Start TeXShell and modify e.g. the Options!Output!
Previewer to use DVIpm, append an exclamation mark '!' to the program
name. Now press F8 (with an primary or edit file set, of course) and
TeXShell will send message to os2execd.exe causing it to start DVIpm
with the required arguments and environment. After termination of
DVIpm os2execd.exe sends the exit code back to TeXShell, and TeXShell
is active again. Everything ok? Start os2execd.exe with the -v option
(verbose) to see the messages sent between it and TeXShell.
