Hi Erik,

I'm afraid you have to clarify what you mean by "memory" in the
context of a program running under OS/2. From a program's point of
view, OS/2 has as much memory as there is free space on the
drive/partition holding the current SWAPPER.DAT file, up to the
system-imposed limit of 512MB per process.

Thus, your progam can use up to 512MB of virtual memory, provided you
have enough swap space on your disk drive.

However, there is an API call available to DosQuerySysInfo() using the
QSV_TOTAVAILMEM parameter that will give you a hint as to how much you
can acquire before you crash OS/2. Note that the returned value is
_advisory_ rather than definite.

Regards

Dave
