Return codes from ICHRLX01

On return from the ICHRLX01 exit routine, RACROUTE REQUEST=LIST checks register 15 for one of the following return codes:

Code: Meaning
0: The LIST request is to continue processing.
4: The LIST request is to terminate processing. For a return code, RACROUTE REQUEST=LIST uses the return code passed as a parameter and possibly modified by the exit. A code of 0 returned after a call for postprocessing is treated the same way as code 4.

Any other return code is treated as an error, and RACROUTE REQUEST=LIST returns to its caller with a return code of 14 (hexadecimal).
