[A83] Re: Symbolic's functions in asm


I tried your example but it crashed. I can't find the error in the code.
Here's the little program I used (quite the same as the example)
Maybe I should swap the old rom page back in or isn't that necessary?

  .org 9D95h
  call mySecOf2
  ld hl,0
  B_CALL(_outputexpr)
  ret
mySecOf2:
  B_CALL(_op1set2)
  B_CALL(_pushrealo1)
  ld hl,2 		
  push hl
  ld hl,name
  B_CALL(_mov9toop1)
  B_CALL(_findapp)
  ret nc
  out (6),a       
  ld hl,(4086h)   
  jp (hl)

name:
  .db "Symbolic",0


Perhaps I'ld better use the parseinp, unopexec,... routines to use the
symbolic functions or won't they work?
