Here's some Microsoft source to turn it off (should work under Borland's 
also, but I haven't tried it):

/*
 *  NUMOFF.C - Turns the NumLock off
 *
 *  cl -Ox numoff.c
 */

#if !defined(MK_FP)
#define MK_FP(seg,ofs)  ((void far *) (((unsigned long)(seg) << 16) | \
                        (unsigned)(ofs)))
#endif

main ()
  {
  *(int far *) MK_FP (0x40, 0x17) &= 0xDF;
  }

Enjoy,
  John
