Code:

irp ty, db, dw, dd, dq {
  macro ty a, [b] \{
    common
    if `a == 'byte'
      db b
    else if `a == 'word'
      dw b
    else if `a == 'dword'
      dd b
    else if `a == 'qword'
      dq b
    else
      ty a b
    end if
  \}
  macro ty [args] \{
    forward
    match a b, args \\{
      ty a, b
    \\}
  \}
}
dd word 3, 4

You need to escape "common", "forward", and "`" too. Otherwise they are processed by the "irp" macro instead of becoming part of the inner ones.

Code:

irp ty, db, dw, dd, dq {
  macro ty a, [b] \{
    \common
    if \`a = 'byte'
      db b
    else if \`a = 'word'
      dw b
    else if \`a = 'dword'
      dd b
    else if \`a = 'qword'
      dq b
    else
      ty a b
    end if
  \}
  macro ty [args] \{
    \forward
    match a b, args \\{
      ty a, b
    \\}
  \}
}

I may also suggest a bit different approach:

Code:

irp ty, db, dw, dd, dq {
  macro ty [args] \{
      if 0
    match a b, args \\{
      else if a eq byte
        db b
      else if a eq word
        dw b
      else if a eq dword
        dd b
      else if a eq qword
        dq b
    \\}
      else
        ty args
      end if
  \}
}

dd word 3, 4

Okay I wanted to make PUSH QWORD 3 compied into PUSH DWORD 3 DWORD 0 but even with the macro seem not so easy
