Cool! With the new rept trick you can even use something like "@b5" Smile

Well, this can be done even with the old "rept" only:
Code:
; this should work with older versions of fasm, too

rept 10 i:0 { @f#i equ ..@@#i }
@@max equ 9

macro @@ dummy
{
  @f0:
  rept 9 i:0,j:1
  \{
    reverse @b\#j equ @b\#i
    common @b0 equ @f0
    forward @f\#i equ @f\#j
  \}
  match max,@@max \{ rept 2 i:max \\{ @@max equ i \\}  \}
  match max,@@max \{ @f9 equ ..@@\#max \}
}

@f fix @f0
@b fix @b0

But with new improved "rept" it can be cleaned up a little:
Code:
; this does the same in a bit cleaner way, using the new REPT capabilities

rept 10 i:0 { @f#i equ ..@@#i }
@@max equ 9

macro @@ dummy
{
  @f0:
  rept 9 i:0,j:1
  \{
    reverse @b\#j equ @b\#i
    common @b0 equ @f0
    forward @f\#i equ @f\#j
  \}
  rept 1 i:@@max+1
  \{
     @@max equ i
     @f9 equ ..@@\#i
  \}
}

@f fix @f0
@b fix @b0

Usage like:
Code:
jmp @f ; goes to (A)
jmp @f1 ; goes to (B)
@@: ; (A)
@@: ; (B)
@@: ; (C)
jmp @b ; goes to (C)
jmp @b2 ; goes to (A)
