LOCAL directive (GFA assembler?)

[phx]

Having a look at the just released Ambermoon sources I noticed the

LOCAL

directive. Can anybody confirm what it does and which assembler supports it?
My guess is that it has the same meaning as defining a global label, but without actually defining a global label, i.e. it separates two blocks of local labels from each other, right? Maybe I would add that to vasm then…

The GFA assembler manual from 1990 does specify a ".LOCAL" directive (https://archive.org/details/GFA_Asse...e/n83/mode/2up) that works like you suggest.

Seems like the code also uses "get" and "push" freely (without defining them as macros). Maybe that's a clue to the assembler used?

Thanks for finding the manual! Seems I didn't look hard enough for it. The directives are all prefixed by a dot, but as I understand this can be configured with an assembler option. And it is the Atari manual.

In the german a1k forum the GFA assembler was mentioned, and the Ambermoon source is definitely incomplete. I would still guess that

push

,

pop

,

get

and

free

are macros, which are defined in the missing part. From their use in the source I cannot determine the function.

It was what I could find (Manual does mention outputting for Amiga though in appendix D.)

Definitely some stuff missing, but just noticed that the source code for "amberstar" is available: https://github.com/jhorneman/amberstar/tree/main



Seems to provide some missing blanks (e.g. definitely written for GFA assembler, provides info on the use of "Push" macro that at first glance makes sense (src/main/xfers.asm)).
