RE: PSDS source informations availability -- RPG400-L

More on the subject of message files. With the example of multiple languages.

Ah!!! You want message files.

Give all your user translations a message number and program for the message number and then have translation copies of your message files.

I will try to explain better.

All my programs call a program to retrieve the translations of the sentences used.
I have a phisical file where are stored the translations of the sentences used by my program.
In the keys of the file there is the program name and library.
Until recently, I used the object name, but now problems have emerged with the copies used to avoid recursion problems.
The copy of a program need to retrive the same translation of the original program.
So I decided to use the source member information.

I hope I explained myself more clearly.

I try to explain my goal. All my programs have to call a generic
program that returns some information based on the name of the source

information at runtime.

Seems an odd design. What does the correlation of source member to
run-time object achieve? What sort of effect comes from it?

This call need to be as fastest as possible, because it is in all my
programs, so I would like to avoid using an API to retrieve the
source info.

The API calls could be limited to those invokers that either do not
pass the source-information or whereby the provided source-information
identifies a QTEMP object name. The invoking executable can be presumed
likely already to be in memory, so the longer code path would be an
issue for the actual access to the run-time object, along with any
paging for the API code [though it might also remain in memory]. Is
there any strong evidence that the additional API work would be an
impact worth the expressed concern; i.e. by actual tests?

Because any caller may be able to compose its own information to pass
[not restricted to the PSDS source-information variables likely, per
even possibly being values generated into the source], is there any
concern for a program spoofing another; i.e. passing information from
the source of a different program? Seems the API approach for all
invokers would eliminate any spoofed invocations.
