Simple and easy to use dialog that lists the ascii characters and gives you multiple clipboard options. The only thing you need to know about it the C button. That stands for clipboard. It just copies the basic format of the value. Everything else should be self-explanatory. Type /ascii to open the dialog.

dialog ascii {
  title "ascii table"
  size -1 -1 136 84
  option dbu
  list 1, 3 4 128 56, size
  text "Character:", 2, 3 63 32 8
  text "", 3, 38 63 25 8
  text "asc value:", 4, 71 63 31 8
  text "", 5, 106 63 25 8
  button "C", 6, 7 73 16 9
  button "C", 7, 71 73 17 9
  button "Clip. w/ $chr", 8, 23 73 39 9
  button "Clip. w/ $asc", 9, 88 73 39 9
}

on *:dialog:ascii:init:0:{ 
  var %x = 1
  while %x <= 256 { 
    did -a $dname 1 Character: $+(%x,:) $chr(%x)
    inc %x 
  }
}

on *:dialog:ascii:sclick:1:{
  did -ra $dname 3 $gettok($did($dname,1).seltext,3,32) 
  did -ra $dname 5 $asc($gettok($did($dname,1).seltext,3,32))
}

on *:dialog:ascii:sclick:*:{
  if ($did = 6) clipboard $gettok($did($dname,1).seltext,3,32)
  if ($did = 7) clipboard $asc($gettok($did($dname,1).seltext,3,32))
  if ($did = 8) clipboard $+($,chr,$chr(40),$did($dname,5).text,$chr(41))
  if ($did = 9) clipboard $+($,asc,$chr(40),$did($dname,3).text,$chr(41))
