Re: Renaming fields

["Booth Martin" <booth@xxxxxxxxxxxx>]

Others have learned that with my code suggestions, best to try it - results
are not always as predicted.  :)

My own preference would be to have a Data Structure, and stand-alone fields
named for the way they'll be used, so as to keep my logic clearer in  my
head as I write.  (See the D-specs in the example I included) In that fasion
I don't need to fuss with prefixes, and can use Sub-routines freely without
having to keep re-copying them for each prefix.

I believe that you can also use the PREFIX keyword in the Data Structure,
but I haven't tried it so best try it out to see what happens.

Can I use the ReName and the Prefix at the same time,
cause now I need to also rename the record format and
I still would like the fields to have a separate name just
to keep it from being confusing.
Thanks

Here's another choice. In the DDS for the logicals, don't mention the
fields at all, just use the same format name as in the Physical file. Then
in the programs, rename the formats. In that case of course you need to be
sure which format you just read. I also use an Externally Described Data
Structure to keep the values saved for undo, etc.

Subject: Renaming fields
Hi all
Could someone help me with renaming all the fields in a particular file.
I have a file Name of PRDMCHM and a Logical File PRDMCHL3.
I would like to rename all the fields in PRDMCHL3 because all the
fields have the same name as in PRDMCHM ( which is obviously
what the Logical file based on.) Could someone give me an example
of how you would do this. I'm not sure if I could do it in the F specs or
should I do it in the D specs. I'm using RPGIV v5r1. All responses will
be greatly appreciated.
Thanks
