Hi,
maybe I'm wrong, but why not using the same file as follows:
1. Read the record (for Delete) into a data structure.
2. Delete the record
3. Read the record (for Update) into another data structure
4. Move the saved/delete data structure into the second/update one (with
either MOVE/EVAL or EVAL-CORR) and replace/reset the key value(s) in the
second data structure
5. Update the second record out of the data structure
Mit freundlichen Grüßen / Best regards

Betreff: Re: D-spec using the same file name twice
Thanks for your reply Booth
Maybe the choice of the word key was the wrong choice Here is my example the
key to the customer file is by customer number
2 records exist the customer file
customer number 1
customer number 5,400,247
They are in fact the same person, so we need to "merge" the data from
customer number 5,400,247 into customer number 1 Update customer number 1
delete customer number 5,400,247
I think it would be easier (maintenance wise) to have 2 separate files, both
keyed by customer number. One file is to update. The other file is to delete
Is this fool proof - no, but in the long run, it will be simpler (my opinion
for what its worth)

Curiosity has the best of me. You are saying "the same key" which says to
me that the file is not keyed uniquely, and that there could well be more
than two records with the same key. Hence my curiosity:
How do you get the particular & specific record(s) that you want to get?

Afternoon all
I know at one point, what I am about to ask is not feasible in RPG
(COBOL is another matter), but the last time I asked this was when I
had first moved over from mainframe COBOL to AS/400 RPG. (TOO many
moons ago)
Can you specify the same file name (physical or logical) more than
once
in
a program?
I want to process 2 separate records by using the same key, or do I
have
to
create a new logical with the same key as the file that already exists?
I almost forgot - we are on V5r4
As always - many thanks in anticipation
