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

Short Answer is no...

The only way to access via a Chain opcode on a SFL is by RRN. 


Thanks,

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

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.
