Hi,
A customer has files that were compressed by COBOL using CDD
definitions. They want to be able to decompress them.
What do you need to know about the file and how it was created in order
to be be to do this ?
They believe Datatrieve will do this. Is this the case ? Are there
other alternatives ?
Thanks in advance,
Mary.

I think I'd start by asking in the ORAREP::NOMAHS::REPOSITORY (CDD) notesfile. This doesn't really relate to the operating system. Steve | |||||

My knowledge doesn't extend as far as knowing what you mean. Has the
customer given the full picture?
You need to find out what really compressed the files. Was it the
LIBRARY command (or callable DCX?) in which case this conference is
the right place? Is this some feature of COBOL in which case try the
COBOL conference? Is this standard RMS compression in which case you
don't need to do anything with the files although a judicious CONVERT
could probably remove the compression?

The customer should know this.
Let's say that the customer has a file and they can't remember how it
was created (e.g. staff turnover) and it doesn't seem to contain the
data that they expect then it sounds as if we should be getting paid
for sorting out the mess but I would start with DIR/FULL and
DUMP/REC:COUNT:3 (or some other small number) for the file in question.
