Question:
   Can I increase the number of file handles to more than 40
in a multi-threaded application produced by C Version 5.10?

Response:
   The maximum number of file handles available for multiple-threaded
applications is 40 by default; this number cannot be increased because
the multi-threaded startup code is unavailable. Consequently, the C
startup code constant _NFILE_, which is used to specify the number of
available file handles, cannot be changed from its default of 40, even
though the default number of file handles in OS/2 is 255.
