RE: Copy book layout - can a compiler tell?

[Thorbjørn Ravn Andersen <thunderaxiom@xxxxxxxxxxx>]

Thanks.  The pointer to the COBOL Programmers Guide was very helpful.  We
have version 3 of the COBOL/400 Users Guide on the shelf, and on page 44 is
the Data Division Map section.

Beautifully described in something even I - hopefully - can understand :)

Thanks again,
