do you think this might have anything to do with a memory leak i'm
having with OS/2 v2.11 ?? i've a REXX script that runs in the
background. when it detects a semaphore file on a RAM drive, it starts
up a DOS .BAT file... the majority of the processing in this .BAT file
is DOS stuff except for about 4 things. these 4 things are OS/2 native
programs which i run from .CMD files via HSTART and use HWAIT to delay
until they are complete... my problem is that after a fresh boot, i've
about 8Meg of RAM that is unused... after each run thru this processing,
i loose memory... after about a day and a half i have to reboot to clean
out the swap file and regain my memory and speed...
