Wanted: Code-Macros explanation

[Arobase, Salle multimédia]

Is anybody out there
who has ever seen a text by Digital Research
explaining the use of "code-macros" with SID-86 ?

If so, would he be kind enough to share it ?

Yours Sincerely,
"French Luser"

I have never seen any documentation for SID/DEBUG macros, sorry.

However, you can find a chapter about most undocumented SID/
DEBUG features (including what I was able to find out about
macros before 1997) in the NWDOSTIP.TXT file which is part of
the MPDOSTIP.ZIP archive available for download on my web site.

The SID/DEBUG macro commands are:

-: Clear all macros
:macroname Define macro (leave with ENTER)
=[macroname] List macros or execute specified macro

I am not aware of a method to define new opcode mnemos for
use in assembly mode (I assume this is what you mean by
"code macros"), though.

The =filename startup parameter in some issues of DEBUG
(as in "DEBUG =filename") can be used to execute a startup
script, for example to "preload" macros as well. However,
this syntax is broken in some versions, unfortunately.

Some issues of SID/DEBUG have several macros predefined,
but they are of limited use for normal users.

Under DEBUG, the -: command is only available in /X mode.

Usage example:

SID
-: ; clear all existing macros
:rosdat ; define a new macro named "rosdat"
D40:0 ; enter the macro body
; leave macro mode
= ; list all defined macros
=rosdat ; execute "rosdat"
Q

Hope it helps,

Matthias
