Dean, I think he means that its still going through those numbers in the loop
maybe something along the lines of this would be faster donno have not tested to see

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