Re: COMP-3 Questions

Regarding which compiler or what error I was seeing, I'm not using any
COBOL compiler. We are developing a product where if a customer
receives a data file which is defined by a COBOL copybook, our goal is
to generate everything you need to load this data into a database on
the same day.

Cannot be done without knowing the compiler and/or knowing if the elementary
items are BYTE or WORD aligned.

For one thing, "COMP <anything> is implementor-defined, meaining each
compiler vendor can make "COMP-3" any format he wants. (vs say,
PACKED-DECIMAL or BINARY, which are standard usage clauses).

For another, even with standard usage, vendors may align - or offer
alignment- options which have the net effect of adding "slack" or "pad"
bytes to a record. Not to mention, the handing of "OCCURS DEPENDING ON" may
be subject to compiler directives.

You can dig up a little more info with these free downloads:

Currently our product works for Oracle and SQL Server ...
the SQL*Loader control file...

FWIW, the above free downloads were some of the credited source material for
Jonathan Gennick's O'Reilly publication "Oracle SQL*Loader: the Definitive
Guide." Good enough for that, should be worth a look for you.
