IBM System/360 System Programmer's Guide

Output from the Accounting Routine: You can write output in two ways:
by issuing console messages or by using the standard systerr output.
1. Console messages -- You can use Write to Operator (WTO) or Write to
Operator with Reply (WTOR) macro-instructions.
2. System output -- You must assemble the following calling sequence
into your routine. The contents of register 12 must be the saThe as
when your accounting routine was entered, and register 13 must
contain the address of an area cf 64 full words.

Exit from the Accounting Routine: You can use the RETURN macro-
instruction to restore the contents of registers and return control to
the operating system.
INSERTING AN ACCOUNTING ROOTINE INTO THE CeNTROl PROGRAM
You can insert your accounting routine into the control prograrr
either before or after the systere generation process. In either caSE,
you must specify that you have an accounting routine. This is done
during the system generation process ty using the ACCTRTN option in the
SCHEDULR macro-instruction.
Inserting an Accounting Routine Befcre System Generation
To insert your accounting routine tefore systerr, generation, you link
edit it into the module library (SYS1.MODLIB) to replace the existing
ffiodule narred IEFACTRT. Detailed information atout using the linkage
editor is contained in the putlication IBM System/360 Operating System:
Linkage Editor, Form C28-6538.
Inserting an Accounting Routine After Systerr Generation
To insert your accounting routine after system generation, you link
edit your routine into the IEFSTERM and IEFJTERM modules of the 18K
scheduler; the IEFSTERM and IEFCNTRL nodules of the 44K scheduler; and
the IEFCNTRL module of the lOOK scheduler. You will be replacing the
existing control section IEFACTRT in these rrodules. The scheduler
modules are in the linkage litrary (SYS1.LINKLIB). The linkage editor
control statements you must use to insert your accounting routine in the
step ana job termination modules of each scheduler follow.
