Provide SPM ITERATE-like analogue with conditions, similar to LEAVE/DOEXIT

An analogous macro to ITERATE with conditions, similar to DOEXIT & ASMLEAVE, would be very helpful to write more understandable code and take advantage of internal z Systems pipelining, instruction prefetch, and branch prediction. (Note: I hav...

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...

SuperC support for VSAM records greater than 64K

We have a customer that wants to use VSAM datasets with record sizes greater than 64K. They rely on SUPERC to do comparisons of test runs. SUPERC does not support record sizes greater than 64K. We would like to see an enhancement for this support.

Conditional Comparison Column Exclusion

We need the ability to conditionally exclude columns from processing. For example, if columns 1 through 5 are APPLE, then exclude columns 6 through 10 in the comparison. We would need to be able to use different versions of this exclusion in the s...

SUPERC Option to Ignore Trailer Record

When processing members of a PDS, or vendor files either online or in batch, the ability to exclude the last line from the comparison without having to physically specify the starting and ending line numbers to process would significantly improve ...

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...

ASMLANGX needs better support for LOUD WTO message redirection

There is a need to be able to capture an redirect the WTO output that is issued in response to the use of the LOUD parameter during ASMLANGX execution. The use of the _BPXK_JOBLOG environmental variable does not work in this case since redirection...

SuperC(option 3.12) High CPU usage

We have a user reporting his observations of very high CPU consumption and running long for PGM=ISRSUPC when any kind of DPLINE control card is involved during comparing of two files. The user says ISRUPC used to be a whole lot faster and consume ...

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...
