The *clerical* people don't want to type 2 characters iff they don't need to - there are some 2 character codes - they want the field to blank out when they start typing into it... And why not? Their VAX ---11/750--- running VMS (and custom screen handler) will let them do it... :-( :-( Basically, I'm looking for a way to have a character field act like a numerical field *on input*. Is there such a way (or hack, I'm not proud). And no, I don't want to clear the field a la CLEAR FIELD...
