- #22: Don't Put Parameter Blocks on Zero Page
-
- Written by: Dave Lyons July 1989
-
- Putting ProDOS 8 parameter blocks on zero page ($00-$FF) is not recommended.
- _____________________________________________________________________________
-
- It is not a good idea to put the parameter blocks for ProDOS 8 MLI calls on
- zero page. This is not forbidden by the ProDOS 8 Technical Reference Manual,
- but then again, it also doesn't tell you not to put parameter blocks in ROM,
- in the $C0xx soft switch area, or just below the active part of the stack.
-
- If you do put MLI parameter blocks on zero page, your application may break
- in the future.
-
- If your parameter block comes between $80 and $FF, it won't work with
- AppleShare installed.
