Re: Re: The best place to begin learning Assembler

Sounds like   um ...fun...

Do you have assembly with the code listings?

00008 18 12  label   LR   1,2

(hmm did I get that right?)

Things I don't know right now:

Assembly idiom = When there are different ways to do things what is the
most accepted. Linkages and stuff too (I have some of that from examples
sent to me in email)

MACROS = what macros are available, what do they do?

Don't you have a disassembler?  I know they produce line labels and
variables that look like L0001 AND V0001 - but perhaps search and
replace will help with that...

How do I access it?  Do I do this inside hercules
or out in Windows (linux)?
