Group W Toolset Release 6.1

Changes Since Previous Release

This document describes changes released in Group W Toolset 6.1, released on 2024-04-14. The previous version was 6.0, released on 2020-07-04.

Older versions of this document are kept in elements with name of the form READ-THIS/xDOTy, where 'x' and 'y' represent the whole and fractional parts of the release level. Example: Element READ-THIS/4DOT0 contains the READ-THIS document that was distributed in Group W Toolset release 4.0.

Group W Toolset documentation is in HTML format. In file #1 of the release are three elements that you should download to the same directory your PC or Web site:

Download GWTS/HTM to GWTS.HTM
Download GWTSDOC/HTM to GWTSDOC.HTM
Download GWTSTOC/HTM to GWTSTOC.HTM

GWTS.HTM defines a frameset that uses the other two documents. If your browser does not support frames (or you hate them), then point it to GWTSDOC.HTM.

Summary of Changes

Correct Bugs

All modules have been re-compiled against CP 19.0 libraries to collect/link changes needed for TDATE$ 2028 Rollover and Daylight Savings Time projects.

New Features in Old Programs

The packaging of Message Control Bank (MCB) programs has been improved:
- We now provide default executables for programs that use MCB (@PASOFF, @PIDSTA, @UDMDEL). The are configured for Application Group 7.
- The element ASGUSE now allows you to choose which MCB you wish to access. See the @USE of MCBLIB$. Thanks to Gary Markowski for this.
- You can still tailor what MCBs can be used by setting flags in GETMCBBDI (see line 50ff). I have changed this to turn on MCB for Application Group 7 only (previously, it was turned on for AG 3 only).
@DAD 1R2 shows total DAD entries.

FAS-FIX/12R2A is local code for FAS 12R2A LIST (from MFD) command.

@MFDPL 2R1 has several changes:
- Output SGSs are now ASCII (was Fieldata).
- Most recent MCT update date and time are now piped as fields 9 and 10 on MCT SGS.
- SLRR MASMTDATE routine is removed.
- Obsolete 6-word EDIT$ packet is replaced.
@PCTPL 1R4 has improved comments re. run start time and TDATE$ versus Modified-SWTIME.

RIBUFDEF has improved comments re. run start time and TDATE$ versus Modified-SWTIME.

RUNINFO 5.5 has improved comments re. run start time and TDATE$ versus Modified-SWTIME.

@SYS 1R6 now shows most recent MCT update date/time.

New Programs

@DWTIME 1R1 is new MASM processor that interprets two octal words in DWTIME$ format.

Note on SLIB Bug

UCF 61620 reports a bug whereby UC compiles get an error with some SLIB levels 2R2 and above. I reported this to Unisys in March 2023 but they have not fixed it (or even created a PLE) as of the date of issue of the present GWTS--more than a year later!

The UC compile error is "*ERROR(MAJOR) UC1052: Redefinition not allowed".

This problem affects @DIFF, @RUNPL, @SHA1PL and @TAG.

Workaround is to create a local version of SYS$LIB$*PROC$.S$LEVEL/H with the line "#include <s$common$def.h>" removed. Unisys says this workaround can break "ID$ and SFDT$ Services feature delivery." So do not change SYS$LIB$*PROC$.S$LEVEL/H directly.

To avoid violating Unisys' copyright, I am not distributing my fixed version of this element. You must create your own if you wish to re-compile the above processors (the ZOOMs provided work). If you create your fixed version in GROUPW*TOOLSET, then the four processors will compile cleanly.
