Re: Declare a key on a subfile... is it possible?

Please clarify.... You want the zip code in the subfile to be unique?  If
so, you need to store the records in a workfile that has the exact same
data as the subfile.  Then you can use that workfile to verify that the zip
code is unique.

Everytime there's a write to the subfile add a write to the workfile that
is keyed by zip code.

Hi!

I want to fill a customer subfile by adding a record only if the zip code
is
not in what I've filled until now in the subfile. Is it possible to declare
a subfile with a key on a particular field of the subfile, so I will be
able
to chain in my RPG ILE program to find this particular value? Or must I
scan
all the subfile record by record to verify the presence of the searched zip
code?

One restriction in this project: I cannot use SQL, only pure RPG ILE for
V4R5 code.
