Updating Load Modules (2 of 2)

Opposite is an extract from the SYSPRINT of the Compile and Link Edit of an amended RDRRTN.

RDRRTN is located from SYSLIN, with the MAINRTN and WTRRTN modules being located due to the INCLUDE statement from SYSIN which is concatenated to SYSLIN.

The RDRRTN already in MAINRTN is discarded as a duplicate, as it is found after the one on SYSLIN.

As RDRRTN is now the first Control Section within the load module, the ENTRY statement for MAINRTN is now required, to ensure processing starts at the correct instruction.
