Current Library mystery

We have a listener program that looks to pull data off a queue.
The code itself is System 36 RPGII and OCL.
There is a line in the OCL that reads:

// IF ?CLIB?/AAALIB PAUSE 

Which, as I understand it, issues a pause that has to be answered if
AAALIB is the current library.  I do not know the reasons why this was 
designed to require a response (and the listener program just waits until 
it gets an answer, keeping the customer queue empty), but it is installed 
at over 100 locations and is not eligible for change.

When I looks at the user profile running this job, the AAALIB is not
the current library, and I have not found where this is being established.
I have almost no OCL or S36 experience, but do not see a likely culprit
in the code I browsed.

Is there a checklist of sources to find the origin of the current library?
