[A83] Re: more push and pop stuff


Since I was in an "I wanna screw up my calc" mood :-),
I just tried it out with the followind program:

---
#include "ti83plus.inc"
  .org 9D95h
  ld hl,0300
  bcall(_disphl)
  bjump(_jforcecmdnochar)
---
I put it on my calc, ran it, and voila,
result:

Asm(prgmX
  786[flashing curor I can use]

It might be a nice trick to avoid the stupid "Done" message.

Though this works, there might be a reason why TI wants of only to be used for 
apps anyone an ideawhat it might be?
