Good afternoon all!

I was wondering if it was possible to edit a PDS member using SMP/E? Let's say I have a PDS member HLQ.MY.PDS(STABLE) and Inside the member STABLE is the following:


Could I use SMP/E to mange this PDS member? If I wanted to apply a SYSMOD to change the member to reflect the following:


I have researched the internet and looked through the manuals, I am perhaps not using the relevant keywords to find this functionality or it does not exist.

I would appreciate any enlightenment on this if possible.

Thanks a lot!!

why would You want to implement a complicate SMPE workflow just to update a PDS

here is a sketch ( incomplete ) of the steps needed

PREPARATION
define the standards , apply/accept apply only
- decide if the updates are full source replacements
- or iebupdte updates
define the naming conventions ( FMID, sysmods )
create the SMPE environment

the fun part of the preparation
build the sysmod for the initial installation of Your pds

UPDATE
create the sysmod
- use the proper sysmodid
- implement the proper PRE/SUP tokens

receive the sysmod
apply/check the sysmod
apply the sysmod
- do the accept processing if the design has it planned

Hi Enrico!

Thanks for your fast response to this question, you raise a very good point or two.

I am just very curious about SMP/E and I have always wondered if it would be possible to do this.

From your reply, I am going to assume that it is possible but not a very good approach?

I will take it from your wealth of experience that my thinking is not the way forward with this.

Thanks!!

Yes, but there are lot of strange restrictions that means it's impractical.

1. The source maintenance program is IEBUPDTE.
2. You must use sequence numbers.
3. You cannot use ./ NUMBER INSERT=YES.
4. You cannot use ./ DELETE. You "delete" a line by making it an Assembler comment!
5. If you are using ++SRC to define a module with no corresponding ++MOD, you cannot specify the module attributes for the DLIB.

In other words, SMP is OK to define a "macro" element such as an Assembler macro or a member that's a cataloged procedure where "maintenance" amounts to replacing the element. If I understand what you're thinking about, it ain't gonna work.
