Re: Move an entire record format as a whole

Well, as Bruce Hoffman said,

If the file is externally described, just declare a data structure as
externally described.
Then, create a second data structure also externally described.

Both data structures are based on the same database file.
On the second data structure (the "save" data structure) use the PREFIX
keyword and automagically rename all the subfields.

Do you database get operation, move DS1 to Sav_ds. Do you process, don't
like results? Move Sav_ds back to DS1.
