Hello, I'm working on Fasm version 1.55 and I need help with next question:

I've a macro like this:

Code:

MACRO     WrtMes  NuMes
{
  MOV       DH, Fila+IncFil*2+4+NuMes         ; Fila
  MOV       DL, Columna-4                 ; Columna
  CALL      WriteXY
  MOV       AH, 9
  MOV       DX, Mens#`NuMes
  INT       21h
}

And I call it from some piece of code like this one:

Code:

  i = 1
  REPEAT 7
    WrtMes    i
    i = i + 1
  END REPEAT

But it gives me an error on lines

Code:

  MOV       DX, Mens#`NuMes
  [...]
  WrtMes    i

Can anyone help me, please?

I'm not sure what labels have you declared for this (it's out of context), but should do it like:

Code:

MACRO     WrtMes  NuMes
{
  MOV       DH, Fila+IncFil*2+4+NuMes
  MOV       DL, Columna-4
  CALL      WriteXY
  MOV       AH, 9
  MOV       DX, Mens#NuMes
  INT       21h
}

REPT 7 i:1
{
    WrtMes   i
}

No time go deep into fasm's macro syntax details, I can just recommend reading the manual and Understanding fasm article.
