Variables and DS are local in a (sub)procedure.

They do noty affect variables in others.

When leaving rhe (sub)procedure the data is "destroyed".

So it does not matter whether you give variables in different (sub)procedures the samen name; they are only available when withint the procedure itself.

Kind regards,

I have confused myself. Again.

Learning about service programs, prototypes, procedures and stumbling.

I I have a service program with which I wish to offer several procedures relating to the various fields in a specific file.

Each procedure will have specific data structures dealing with the fields related to that procedure. I would like to use the same data structure name in several procedures although the fields will be different in each data structure. It's not letting me do that. Then, when I changed the names of the data structures it tells me that the field names in the data structures are already defined.

So... how do I make data structures and field names that are local to the procedure in which they reside? Or is that a you'll-be-sorry wish?
