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:

Code: Select all

	org 327689
	ld a,456
	ld hl,123456789
	ld (hl),a
loop: jp loop

and will actually create a valid object file. However the contents will be:

Code: Select all

	ld a,200
	ld hl,52501
	ld (hl),a
	jp 15

Once you realize that PASMO assembles all 8 bit numbers as modulo 256 and 16 bit numbers as modulo 65536 - even the incorrect ones - then it makes sense, but it's so easy to mis-type a number or accidentally enter something that should be out of bounds that the least an assembler should do is flag it as a warning. Once you are more confident in your coding abilities then this shouldn't be a problem but when you are just starting to learn machine code you shouldn't have to worry that your assembler is hindering your efforts instead of helping you.
