Re: New to machine code...seeking assistance.

I would not reccomend the PASMO assembler if you are just starting off with assembly. It does not validate numbers after commands properly which can lead to unexpected results e.g. the following program will quite happily assemble under PASMO with no errors being generated: org 327689 ld a,456 ld hl...
