I'm confused; I see:
#13.1.4 "z/OS V1R7.0 MVS Assembler Services Reference IAR-XCT"
___________________________________________________________________
13.1.4 Input Register Information
Before issuing the IEANTRT callable service, the caller does not have to
place any information into any register ...
... but:
#13.1.7 "z/OS V1R7.0 MVS Assembler Services Reference IAR-XCT"
___________________________________________________________________
13.1.7 Syntax
Write the call as shown on the syntax diagram. You must code all
parameters on the CALL statement in the order shown.
CALL IEANTRT ,(level ,user_name ,user_token ,return_code)
... is this a special CALL that does not require that the
address of an available RSA be placed in R13, or is that
assumed even when the RM says it's unnecessary?
