get the last label to compose a new label.

for example:

Code:

macro localthing {
local .a
append do1:
             add eax,[var]
             jmp .a
append do2:
             mov eax,2
             jmp do1
append var dd ?
.a:         
             ret
}

stuff:
         localthing
         mov ebx,eax
.local: 
         localthing
 
.verylocal:
         add eax,[.localvar]
         localthing
 

tryit:
       call stuffdo1
       call stuff.localdo2
       mov ecx,[stuff.verylocalvar]
       ret

the goal is to create local label implicitlly, then you can compose labels with a syntax automatically

fasm don't have append keyword.
you can append equates.
and later use the final equate as a string of stuff added one by one.

but here, the idea have nothing to do with values of labels, but names of labels.

i don't get where in the manual are the stuff related to labels in fasm1.

i don't use fasmg at all because i'm a dinosaur and like fasmw too much to go to fasmg.

then, be able to compose labels inside my code can help to do OO stuff

If that's the only reason, you really should try out fasmgw that comes with fasm2 release.

Code:

macro localthing {
local .a
.do1:
             add eax,[.var]
             jmp .a
.do2:
             mov eax,2
             jmp .do1
.var dd ?
.a:         
             ret
}

stuff:
         localthing
         mov ebx,eax
stuff.local: 
         localthing
 
stuff.verylocal:
         add eax,[.localvar]
         localthing
.localvar dd 0
 

tryit:
       call stuff.do1
       call stuff.local.do2
       mov ecx,[stuff.verylocal.var]
       ret
