Assembler

System Variable Symbol &SYSRMODE

I need a way to determine the RMODE of a CSECT from within a MACRO, if the RMODE was set via either an RMODE statement, or a CATTR statement.

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...

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.

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.

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".

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.

Flag SS instructions with a (probable) incorrect use of implied operand length

Please consider the following two MVC instructions, both of which use the implied length of the first operand: MVC FULL1,FULL2 perfectly reasonable MVC FULL1+2,HALF explicit length of 2 is obviously missing…FULL1 DS FFULL2 DS FHALF DS H* LTORG The...

Allow HLASM to run on an x86 Linux server

Currently the HLASM build only works on a Linux system running on a zSeries mainframe, this restriction means we must purchase an IFL and mainframe storage to run just one Linux server, a TPF Toolkit guest.This IFL runs on the same hardware as our...

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'

Improve how the move instruction with differing lengths is handled

There has been a lot of discussion on the assembler forum on issues with the MVC and differing length fields. Sample macros have been added that help assist in this area. Many customers have home written macros. Example statements include: 'Storag...
