Re: I hate Activation Groups....

For those still thinking about this, the answer to the problem is well
documented within the ILE Concepts manual. In short:

-symbolic links to the service program are converted to physical addresses
upon program activation.

-program activation occurs as part of an HLL dynamic program call.  Once a
program is activated, it remains activated until the activation group is
deleted.

Since the original ILE program was running in the default activation group
(which never get's deleted), we should expect each subsequent call to crash.

Anyone who isn't comfortable with ILE yet, should really take the time to
read the concepts manual. Unlike most IBM manuals, it was written quite
well, and it does a great job of explaining ILE.
