jaytea the first post of alabama was like this

on *:dialog:chr:init:*:{
  var %x = 33
  while (%x < 127) { did -a chr 1 %x | did -a chr 2 $chr(%x) | inc %x }
  var %y = 160
  while (%y < 255) { did -a chr 1 %y | did -a chr 2 $chr(%y) | inc %y }
}

as i mentioned, using !isnum operator would make it shorter and faster in my opinion, but as you said, different methods

on my last example i think it is fine, since its ignoring the characters between 127-159

on *:dialog:chr:init:*:{
  var %x = 33
  while (%x < 255) {
    if (%x !isnum 127-159) { did -a chr 1 %x | did -a chr 2 $chr(%x) }
    inc %x
  }
}

but thanks for the example, now i understand it
