That depends. A module linked with RENT will be loaded into SP 251 or
SP 252, depending on whether the library concatenation is authorized.
There are additional variables if it is linked REFR or is LPA
resident.

That's legitimate if they serialize the access and run with the proper
PSW key. In your case the program probably should have been bound as
REUS.
