Re: Is this possible and if so

"The problem I see with help files is constantly making changes as we enter 

new code violation codes or delete ones no longer needed."

You are absolutely right.  Help text should be for constant information on 
the application and on situations where codes are constant.  You can do 
(in theory) something like this;

DOU     *IN03

        EXFMT   MAIN

        IF *IN03
                ITER
        ENDIF

        CODE    CHAIN   CODETABLE

        IF %FOUND(CODETABLE)
                EVAL SCREENCODE = CODEDESC
        ELSE
                EVAL SCREENCODE = 'INVALID CODE ENTERED'
        ENDIF

ENDDO

Just an idea... good luck!
