Automatic Binary Optimizer for the Operating System

Since years, there is the ABO available for COBOL. The latest z/OS always supports up to minus two generations of hardware. So after you update a z/OS and a machine, you still can't benefit at all from the latest hardware. The idea is to add a sim...

Multiple Image Registry for zCX

This is a request for Enhancement in z/OS Container Extensions (zcx or classic zCX). zCX currently allows only one secure image registry & its certificate to be specified in its configuration. If we want to change the image registry, we need t...

This is an additon for ZOS-I-4417, but it would also be usefull if it could be provided for the existing JWT validation... With RACF be able to validate JWTs, there should be a service avalable to extract the information out of the JWT after it go...

64-bit latch services support AMODE(64) but not RMODE(64). The irony of this is obvious.

This support, which is trivial, should have been done as soon as RMODE(64) was supported.

Stacking PCs only support 31-bit via the ETDEF service PROGRAM or ROUTINE. The hardware has supported 64-bit PCs for over twenty years. This support needs to be added.

Allows PC routines to be located above the bar.

z/OS services document which general and access registers are altered after service is invoked, but floating point registers are not so documented. Some JSON services corrupt floating point registers without documenting this fact (F0).

Helpful in programming.

The LOAD service does not allow load modules with SPLIT attribute to be loaded into ADDR and ADDR64 areas. This makes loading a SPLIT module into ECSA and 64-bit COMMON difficult, as one must code two separate modules.

Simplify z/OS LOAD and utilize SPLIT as intended

For the LOAD macro, it appears that the parameter EXTINFO was added wth the express purpose of avoiding a call the CSVQUERY. However, CSVQUERY must still be invoked to get module attribute information, such as RENT, who loaded it, etc. EXTINFO should return this information as well.

Finish the goal of avoiding a CSVQUERY invocation.

For STORAGE RELEASE and FREEMAIN, if conditional, R0 should have a reason code which indicates the cause of the failure. Currently R0 contains no defined values at request completion.

When debugging with conditional STORAGE RELEASE and FREEMAIN, z/OS knows the reason for return code 4, but does not disclose it to the invoker. This makes investigating the cause unnecessarily difficult.
