Re: A92: Line 1111 Emulator




Line 1111 Emulator happens when an address is odd too:
if you compile this: you get a Line 1111 Emulator [doesn't get Address Error
though]:


 @program prog_code,prog_name

prog_code:
  move.l  2(PC),a0
  jsr     flib[idle_loop]
  jmp     (a0)
  rts
prog_name:
 dc.b    "Line 1111 Crash",0

 reloc_open
 add_library flib
 reloc_close
 end

What about the idea of people at ti having written routines that casually
redefine $Axxx or $Fxxx for use in rom-routines. If then a fargo program is
started and calls a rom-routine that usually first sets the emulating
routine
and then calls the redirected emulator without this initialisation the calc
crashes( I haven't tried it ). On my atari 1020 that was a usual way to do
IO

graphing...), it was undocumented and worked well until Atari changed this
for
other purposes. AK
