If you want to generalize that routine so that it will print only the characters needed you can do it like this:

[code]SUB TX_DEC
  wDividend     VAR     tmpW1
  wDivisor      VAR     tmpW2
  wResult       VAR     tmpW3
  wIdx          VAR     tmpB1
  wChar         VAR     wResult_LSB

  \ SB  __PARAMCNT.1
  \ CLR __WPARAM12_MSB
  wDividend = __WPARAM12

  IF wDividend > 9999 THEN
    wDivisor = 10_000
    wIdx = 5
  ELSEIF wDividend > 999 THEN
    wDivisor = 1_000
    wIdx = 4
  ELSEIF wDividend > 99 THEN
    wDivisor = 100
    wIdx = 3
  ELSEIF wDividend > 9 THEN
    wDivisor = 10
    wIdx = 2
  ELSE
    wChar = __WPARAM12_LSB + "0"
    TX_BYTE wChar
    widx = 0
  ENDIF

  DO WHILE wIdx > 0
    wResult = wDividend / wDivisor
    wDividend = __WREMAINDER
    wChar = wChar + "0"
    TX_BYTE wChar
    wDivisor = wDivisor / 10
    DEC wIdx
  LOOP

  ENDSUB[/code]
