On your second question, you might do something like this 

[color=blue>GET_VALUE:
 ]  theVal = 0
  DO
    key = SCAN_KEY
    IF key = Enter THEN EXIT
    theVal = theVal * 10
    theVal = theVal + key
    INC keyCount
  LOOP UNTIL keyCount = 3
  RETURN[/color]

This routine will allow up to three keys and can terminate with an enter key -- that way you can get one- or two-digit values.
