Subject: Re: Saving Si And Di?
 
Your assembly routine may be altering the registers. Right from the manual,
in the Users Guide, under Saving Registers:
  'For external routines and ASM statements, you need to save the SI, DI,
BP, DS, SS and SP registers.
      -> If your routine doesn't change the registers, you don't have to
save them. However, most BIOS and DOS interrupts destroy most registers, so
it is better to be safe than sorry. '
