    Collecting Db2 Integrated Synchronization counters in IZDS

    IBM Z Decision Support currently does not collect Db2 Integrated Synchronization IFCID 2 counters. In Db2 component table DB2_IDAA_STAT_S_H/D there is column REPLICATION_CPU, but is only populated with data for CDC replication. Since we have migra...

    Allow LIST RECORD consumption to be drifted to ZIIP processors.

    Now, IZDS and IZPCA allow the derivation of a COLLECT to ZIIP, but it is not possible to do the same with a LIST RECORD.It would be good to study the possibility of adapting the LIST RECORD as well.

    True length of DSECT

    There should be a method (perhaps a new parameter) that would cause the "length" attribute of a DSECT to return the actual size of the dummy section, rather than simply returning a value of 1.

    Provide a new system variable symbol to provice the current RMODE value

    Useful in macros to determine current RMODE at assembly time.

    New extended mnemonics needed for branches/jumps following TMLL and friends

    New extended mnemonics are needed for "branch/jump [not]mixed" instructions to be used following the newer Test Under Mask instructions. The older TM instruction never sets CC=2, so the older branch/jump [not]mixed mnemonics (JM, JNM and similar) ...

    Permit named PUSH/POP statements

    When the assembler reaches an END statement, and there remains unPOP'd PUSH USINGs, it issues ASMA138W . Well, in large complex assemblies, finding the unPOP'd PUSH or PUSHs can be rather a challenge. In my own coding, I have solved that by replac...

    Fully support 32-bit EQUs (maybe even 64-bit EQUs as well)

    The assembler's support of 32-bit EQUs is arcane, to say the least. Consider: EQU1 EQU X'80000000' EQU2 EQU X'80000000'+1 EQU3 EQU X'7FFFFFFF'+1 The EQU1 and EQU2 statements are fine.The EQU3 statement gets flagged with ASMA074E. I do understand t...

    Flag RX instructions with index but no base register

    It has been a common malpractice since more than half a century not to use a base register but the index register in rx instructions, e.g. L Ra,100(Rb) instead of L Ra,100(,Rb). Historically, this implied some performance penalty (AFAIR), nowadays...

    Improve ability to define structures with power-of-2 size

    When writing assembler code, it is often desirable or even necessary to define a structure with a length that is an integral power of 2. Reasons for such might be to avoid crossing a cache-line boundary; to be able to allocate an array of structur...

    Enable the ability to run the COLLECT batch process of different components in parallel.

    When a COLLECT process is executed, some DB2 resources are allocated that prevent processes that collect data for different components (CICS, DB2, MVS and so on) from being executed in parallel. If the COLLECT processes of different components cou...
