Cobol program from IDDcopy book? thanks a lot,

Hello,

Where did the term "IDDcopy" originate? This is not a term i've ever head of.

If this is some kind of COBOL "copybook" that describes some database info, it is used the same as any other colpybook.

The program still has to read the database - probably pointing to the copybook as the place to place the data returned from the read. If a write is being issued, the data would be moved from whereever to the copybook fields, then the add/update/delete is issued.

With google it looks like IDMS. Can you locate your IDMS documentation?

The I is IDMS and the DD is Data Dictionary. What you are actually referring to I do not know - I have had little to do with the DD. Once again, the best place to ask is your work-place as I suspect how you use it is installation specific.

thanks, all,

you are correct, Iddcopy is used for send or receive data from IDMS database, it's a kind of copybook in COBOL,
thanks a lot
