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

Showing 37

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...

Identify concatenation number in SRCHFOR of sequential DSNs

When a SuperC SRCHFOR operation is performed on a concatenation of PDSes, the listing will identify a concatenation number for the data set containing the member where the string was found. But when the concatenation is of sequential data sets, th...

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.

SuperC read Panvalet

Please add support for reading Panvalet to SUPERC.

SuperC - Do Not Report Spacing Changes Unless Within Quotes

There is an existing option, DLREFM (suppress reformatted lines from the listing) which although it does suppress the reformatted lines from the OLD file, it does not suppress them from the NEW file. Another option, REFMOVR, suppresses reformatted...

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.
