ILE Concepts

Hi everybody,

I need some comments/strategies about ILE Concepts.
A company worked since years as follows:
- One Source one Object (Service-Program or Program)
- a Service-Program could include 1 to n (exported and a few internal)
procedures
- Binder Language was used in the way, it was maintained before creating or
updating the service program. (They even had a tool which generated the
binder language automatically by scanning the source)
- The signature was kept static, i.e. Signature Name = Service-Program name
- Even though the signature was static, the previous export blocks are
stored in the binder source just to see what procedures were added.

With this method they could easily add new procedures to service programs
and transfer single service programs from the development system to the
productive system.
In the case of the company they had to implement the application and fixes
on different customer machines. Because the tool was a development tool, the
customers had to call the exported procedures.
... and until now it worked without problems.

Now a new (java) guy/leader (who knows everything better) came and told them
everything they did were bullshit.
He wants the following:
- Service-Programs are compiled/bound without binder language (i.e. EXPORT
*ALL)
- After the binder language is retrieved (and the signature get modified,
i.e. ALL SERVICE PROGRAMS will get the SAME NAME, i.e. Company name =
SIGNATURE).
- Then an UPDSRVPGM is performed to include the new Signature in the
Service-Program

- if new procedures are added, again the Service-Program is again created
with EXPORT *ALL, and the binder source retrieved.
- the binder language is retrieved again, and only the signature has to be
changed.

IMHO this cannot work ... at least not without recompiling everything.

Someone can tell me what happens if ALL Service-Programs get the same
signature?
Are the right service-Programs still found or are just ALL service-programs
activated at the same time?
Are the right procedures still called if all Service-Programs have the right
signature?

What do you think about this new strategy ...and was the old one so silly?

Mit freundlichen Grüßen / Best regards
