Z80-ASM is a Z80 assembler and debugger.
Each Z80-ASM package contains a compiler for the Z80 assembling language and a monitor including an interactive debugger. Compiler is a two-pass one, which knows all documented Z80 instructions. It has labels, comments and since 2.1 can even evaluate constant arithmetic expressions.
Debugger is interactive, it shows content of all registers, memory, stack, program. You can trace program, trace it step by step, modify program, registers and content of memory, load and save parts of memory.
Everything you need to run the Z80-ASM is Linux or DO$ system (it should also work on other Unixes) and GCC/DJGPP compiler.
To install the Z80-ASM you must do following:
· download and unpack the archive
· cd to the just created z80-asm directory
· read the INSTALL file
· according to instructions you've read install the Z80-ASM :) but typically a 'make' will do what you want.
