Unchanged,  I got 91 files opened with your program on my Warp pc.  The
value changes depending on what parent programs have done -- for example,
if something in your conig.sys (run=),  or a WPS object,  has called
DosSetMaxFH(),  it will impact your programs too.

If you need more than a dozen files,  it is _never_ safe to assume the
default on your PC will be the same on other's.

I made your program allow 200 files by calling the watcom function
_grow_handles(200).

I think the IBM CRT will automatically cope with a DosSetMaxFH() --Watcom's
doesn't -- it needs you to call _grow_handles (which will call DosSetMaxFH
for you) to expand its internal handle table.
