I am not familiar with DOSCMD, but this is what I would do...



JSR save80toCA ; at the beginning of your program

; ... your code that disturbs 80 to CA

JSR swap80toCA ; before calling DOSCMD

; call DOSCMD

JSR swap80toCA ; after calling DOSCMD

; ... more of your code that uses 80 to CA

JSR swap80toCA ; might want to do this again before quitting your code.



I did something similar to this in "Apple-1 for Apple II" to save and
restore critical pages of memory that I clobber with my code.
