Code:

 a1 EQU macroA
 a1 EQU macroB
 a1 EQU macroC
 irpv v,a1 { .branch#num: v }

I want get:
.branch1: macroA
.branch2: macroB
.branch3: macroC

How do this for irpv ?

With fasmg it would work as simply as you imagine:

Code:

a1 EQU macroA
a1 EQU macroB
a1 EQU macroC
irpv v,a1
  .branch#%: v
end irpv

But with fasm 1 you need to maintain a counter manually:

Code:

a1 EQU macroA
a1 EQU macroB
a1 EQU macroC
__c equ 1
irpv v,a1 { rept 1 num:__c,next:__c+1 \{ .branch\#num: v
                                         __c equ next \} }

Could in fact be a little simpler:

Code:

a1 EQU macroA
a1 EQU macroB
a1 EQU macroC
__c equ 0
irpv v,a1 { rept 1 num:__c+1 \{ .branch\#num: v
                                __c equ num \} }

Ho do jmp nxt branch ?
I mean:
macroA must jmp .branch2
.branch2: macroB must jmp .branch3
.branch3: macroC must jmp .branch4
.branch4:

I try this work.

Code:

   __c equ 0
irpv v,a1 { rept 1 num:__c+1 \{ .branch\#num: v .branch_\#num
                                .branch_\#num:
                                __c equ num \} }

Can't you do that?

Code:

macro macroA {local end_label
jmp end_label
...
end_label: }

a1 EQU macroA
a1 EQU macroB
a1 EQU macroC
__c equ 0
irpv v,a1 { rept 1 num:__c+1 \{ .branch\#num: v
                                __c equ num \} }

This variant I try.
But some times local labels in macro not good, and create problems if I want do loop from macroC to macroA
