To get anything "useful", we need to write backspace-space-backspace.

You mean only 1 backspace want do it?
Still what would be the correct assembler routine?

You problem with the backspace could come from the keyboard
handler itself, some OS (IIRC: DOS&DOSKEY) remove the last recent
character in its buffer already when receiving a BACKspace.

So if the buffer is empty any BACKspace would be ignored.
You then may need to check on the last received scan-code
in the buffer to find 'last key' pressed was a BACKspace.

My own written KEYBD routines produce code 08 for BACKspace
and leave any action on it to the application.

But as it seems you like to write a SIMKEY function for winXP,
you better check on API-opportunities then.

for win32 he got for instance "User32.keybd_event"

there another as well, "SendInput", that is new, where he can send an array, but
I think the docs are misleasing on that one, and I didnt get it working
last time I tried. "User32.keybd_event" is easier to set up and I know it works.
It syntesize a key into the os, as if it came from the keyboard.
