A few months ago someone asked how to have more than 15 files open at a time.
Larry Shurr suggested using funtion call 67h, as follows:

union REGS inregs, outregs;
inregs.h.ah = 0x67;
inregs.x.bx = number_of_files;
int86(0x21, &inregs, &outregs);
(slightly modified for Turbo C)

The problem is that this doesn't seem to work, at least for me. It also
causes memory allocation problems for ATs under DesqView (ie malloc etc
can't reserve any memory). Am I missing something, or is this method wrong?

Thanks in advance for any replies.
