Question that could take me all day to answer empirically:
If an RPG program calls a service program that leaves files open,
then the program ends with SETON LR, should the files opened in the
service program remain open, within the job that called the program?
It's not just files in a service program that would be left open. Files
in other modules of the program would also be left open.
RPG modules are standalone. If a program (or service program) has
several modules that use the RPG cycle, each module has its own LR.
Setting on LR in the main procedure of the program-entry module only
affects that module.
Files get opened when the first procedure in the module gets called, or
if they are USROPN, when there is an OPEN for them.
Files get closed by
- a CLOSE opcode
- activation group ending
- the cycle-main procedure in the same module ending with LR on or
ending abnormally
