AFAIK it should not be required. From reading your many and interesting posts to this list I realize that we must be contemporaries (possoibly I started programming before you - circa 1963 on a ICL1500 aka RCA 301 in assembler or directly punching machine code into punch cards). I do appreciate your responses as they always are helpfull and when them flame wars flare up you remain sensible. Thanks again ChrisG
