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...

Reentrant check fails when labels in an RSECT are used to map dynamic (writable) storage

When using the label of a field defined in an RSECT to map some other (writable) area of storage pointed to by a register, the reentrancy check is applied. This causes message "ASMA036W" to be issued even though there is no reentrancy violation. A...

HLASM ADCON Type for Weak External Reference

HLASM would provide a new ADCON type (e.g. W or WV) that would generate an address constant containing a weak external reference to a symbol in another module to be linked with the module containing the W ADCON reference. This new ADCON type would...

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.

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...

Provide the option to make new RENT Assembler module against SIIS.

Provide the option to make new RENT Assembler module against SIIS(Store into Instruction Streams). Upward compatibility disappears in terms of performance by SIIS.On z13 sometimes more visible than on z196 because the bigger L2 I- and D-caches are...

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...
