- Receive Journal Entries exit program. Wait, where is this exit program?

Rob:

RCVJRNE EXITPGM() -- it's a parameter on the command.

The command includes some selection criteria and other parameters that should help in making the choice between the command or the scan exit point, if those are the choices.

RCVJRNE is only going to associate an exit program with objects related to that journal and only for as long as the command executes. The Scan on Close exit point is associated with everything in the root file system and all processes accessing the root file system (more or less, and depending on configuration).

If I was simply going to monitor a known directory for streamfiles being deposited, I'd probably start with just reading the directory entries rather than using either RCVJRNE or the Scan on Close exit point. I'd only look deeper if other elements brought the need.

Both journaling and scans have many additional considerations that require thought. For basic monitoring of directory entries, thoughts _might_ be limited to (1) does a new directory entry exist? and (2) can I now do something with it, i.e., is anything else still busy with it? Each loop through the directory entries gives a chance to test end-status, BTW.

But 'basic' monitoring for existence is a relatively minor task compared to the capabilities of each of the choices. I'd simply suggest going with complexity that's appropriate to the requirements.
