I'm thinking this might be what you're looking for:
Increment the number of file handles available to a shell process
(e.g. a REXX program started by the CMD.EXE) by the amount of n. (see
also Maximum files per session; tested only in WARP 4 with Fixpack #6)

Thanks, this really works fine, this was exactly what I was looking for.
However I still like to know how OS/2 handles message files, because I investigated the program (written in C) that was causing the problem of not having enough filehandles had several message files open, and the only api call that is used however is DosGetMessage(). Is it possible to close the message file?
Also I modified the program in such way that at the very beginning in a loop several files where opened. Of those files I displayed the file handles of the open file if opened succesfully, and observed a jump in the filehandle numbering: after filehandle 7 was opened the next file handle was 13, is this due to the messagefiles that are used? Can any one give me an explanation for this?
