I am having trouble porting a program to OS/2 under Microsoft C that
I've successfully ported among DOS and SCO UNIX systems.  The program
requires at least 16 files to be open at one time.  This is easily
handled on both DOS and UNIX.  The files are opened by the standard
"fopen" library function.  I find that OS/2 limits me to about 14 user
files at one time (probably a 20 file total limit).  I've investigated
the FCBS parameter in CONFIG.SYS and the DosSetMaxFH function in the
OS/2 library to no avail.  However, if I use DosSetMaxFH in conjunction
with the OS/2-specific DosOpen function I can open the desired number of
files.  Converting all fopens and fprintfs to the DOSxxx library
functions would make the program much less portable - so this is not an
acceptable answer.

Does anyone know of a way to open more than 14 user files under OS/2
using the Microsoft C 6.0 compiler?  Any help would be greatly
appreciated.
