- Does anyone here happen to know anything about how Abacus' Super-C
- (version 2) on the C-64 uses zero page memory? The manual doesn't
- really explain this (unless I missed something). The only hint is
- that it says that when you use the call() function, you can use
- $20 through $30, but I suspect that that is only during the call().
- I need a about five bytes of zero page for an IRQ interrupt handler.
- Thanks in advance for any clues...
