Well that's what I get for not reading the whole thread first.  It's the *SRVPGM that uses a file that is a problem.

That isn't quite right.  I just ran a test on v6.1

RPGLE program AGTEST created with CRTBNDRPG
     h DftActGrp(*No) ActGrp(*Caller)

     fmcphmo    if   e             disk

      /free
         read mcphmo;
         dsply 'did it!';
         return;
      /end-free

CLP program AGTESTCL created with CRTCLPGM
             pgm
             call       agtest
             rclrsc
             call       agtest
             endpgm

According to your explanation, the second call to AGTEST should fail because it is trying to read a file that is closed.  I did verify that rclrsc closes the file, but it is back open when AGTESTCL ends.

Still looking for an example of the problems that this causes.  I have a client that used *CALLER from the default activation group almost exclusively, and I could never convince them it is a problem because they have done it that way for years.

Luis,

In general:
- Real ILE programs are intended to run in 'real' activation groups, not 
in the default activation group. OPM compatible programs - 
DFTACTGRP(*YES) - are intended to run in the OPM environment; they 
behave differently.

Specifically:
- Real ILE programs stay active until the activation group ends. If a 
real ILE program runs in the default activation group, the only way to 
end it is to end the job.
- OPM compatible programs react to RCLRSC as OPM programs do: they close 
their files and on next activation behave as if they were called for the 
first time. When an ILE program runs in the default activation group and 
a RCLRSC is issued, the files are closed, but on the next call the 
program will not reopen them.
