IBM High Level Assembler for z/OS and z/VM

Some SuperC options should cater for longer lines

A number of SuperC compare options are currently rejected for datasets with an LRECL > 256: ISRS013W CERTAIN "DO NOT PROCESS" OPTIONS ARE REJECTED DUE TO LI NE LENGTHS > 256. OPTIONS RESERVED FOR PROGRAM SOURCE DATA. ISRS016W MOVE LINE DETEC...

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.

Structured Programming Macros: support parenthetical grouping of logical conditions via parentheses

Support for parenthetical grouping of logical conditions is currently only possible by using the ANDIF and ORIF operators. This is because the Structured Programming Macros do not support the use of parentheses to specify logical hierarchy of cond...

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...

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...

Additional SuperC returncode for changed data compare

Batch invocation of SuperC (ISRSUPC) currently gives two "normal" completion return codes, 0 for "No differences" and "1" for "Differences found". A third "normal" completion return code of 2 would be advantageous for those cases where there are n...

ISPF ISRSUPC to permit FINDALL to work against individual PDS members

Add an MVS ISPF ISRSUPC/SuperC search option similar to FINDALL that works against discrete members of a PDS. ISRSUPC's FINDALL process option returns a positive match only if all SRCHFOR criteria are met. This works fine for a sequential file; ho...
