// Example showing how to use KickAsm segments to compile meant to be transfered to zeropage before execution.
|
|
// The linker-file defines the ZpCode segment to be on zeropage and does not include it directly in the PRG-file (by excluding it from the Program segment).
|
|
// Instead the compiled code is added as an array of chars in "normal" memory - and transferred to zeropage at the start of the program
