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

Assembly Listing Headers - Four lines of USINGs information is not enough

Currently, the page headers area for Assembly listings is limited to 8 lines: title line, page number, column headers and... from two to four lines of active USINGs information. I use named USINGs a LOT! So much so, that I frequently blow through ...

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...

Option to check instruction-to-field mismatches

Looking for an option which when specified would have HLASM report instances where the instruction mismatched the data that it would operate on. Like "check that I am using instructions that match the data length of the field".

Allow fields >= 64k

The assembler currently only supports the definition of fields less than 64k bytes in length. The assembler should be revised to support the definition of fields greater than or equal to 64k bytes in length.

COPYLIB DD for COPY code, SQLLIB DD for SQL INCLUDE

Assembler copy code and macros are distinct types of elements that can be mutually dependent. Because they are read from the same SYSLIB DD they need to be assigned different names. A COPYLIB DD for copy code would support matching named macros an...

Identify SIIS issue before moving to z13 / z14

It is known that Assembler code using "Store into Instruction Stream" (SIIS) does not perform as well starting on z13 hardware due to a change in cache structure. It would be beneficial to have an option in the HLASM Toolkit to identify code which...

HLASM toolkit needs to support line-mode programs which use PUTGET and TGET macros

The HLASM Toolkit needs to support line-mode programs such as those which use the PUTGET and TGET macros/services. When such programs are tested using the Toolkit, the macros return invalid command buffer data. The Toolkit tests the programs as 32...

ISRSUPC Support Of Datasets Created With Large Block Interface

Request for ISRSUPC (batch program for SUPERC compare) to support datasets created with Large Block Interface.

Allow the underscore separators to improve readability.

From the assembler list (ASSEMBLER-LIST Digest - 3 Jun 2012 to 4 Jun 2012 (#2012-101)) Allow underscore in values: for example allow the developer to code:A DC F'2_147_483_647' rather than A DC F'2 147 483 647' or A DC F'2147483647'
