As simple as it sounds, I can't think of a way to
toggle the NumLock key (through software of course!).

It's not anywhere in the ASCII charts, buy I'd like 
to do this through software since it's on everytime
I boot my machine, and I'm getting too lazy to reach
alllll the way over to the keypad to kill it.

anyone? anyone?

Hi.  Just zero out the word at address 0040:0017h and this will turn everything
(caps/num/scroll lock, insert toggle, etc.) off.  Here's some assembly-language
code you can try:

; NONUMLOK.ASM.

		.model		tiny

Code		segment
		assume		cs:Code
		org		100h
Start:		mov		ax,40h
		mov		ds,ax
		mov		word ptr ds:[17h],0
		mov		ax,4C00h
		int		21h
Code		ends
		end		Start

Tschuess,
David Paschal

The 1st Edition of PC Magazine's DOS Power Tools book comes with a disk
containing two 46 byte com files entitled NUMOFF.COM and NUMON.COM.
Unfortunately, they did not include the source.  However, I think these are
probably available for download from the PC Magazine BBS.

Notice I said the 1st Edition.  The 2nd Edition of the book, which has been
updated to cover MS-DOS 5.0, no longer has these two programs on the software
disks that come with the book.

I am sure there are public domain programs which do the same thing, but I
don't personally know of any.

Newer systems provide a setup option which allows you to select the default
setting which NUM LOCK should have at the completion of a system boot.
Perhaps your's has this option and you just didn't notice.

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

If they're only 46 bytes each then uuencode them and post them here.
If somone wants the code they can look at the executable with DEBUG
and figure it out.  That should be a piece of cake since they're so
small.  As far as the BBS is concerned, it's no longer in existence
as a BBS.  It's been converted to a section of CompuServe called
PCMagNet (GO PCMAG).
