Sort/Merge Utility from MVT
Updated 03/11/2024
Tom Armstrong has released an updated OS/360 MVT Sort/Merge (source is CBT File #1036). I have updated the Sort/Merge installed on SYSCPK to this version, so I am also updating the installation instructions here.
Tom Armstrong also provides extensive documentation on his version of the Sort/Merge, which are available for download from my site: Tom.Armstrong.OS.360.Sort.Merge.v01.1.Installation.Guide.pdf Tom.Armstrong.OS.360.Sort.Merge.v01.1.Application.Guide.pdf.
Note: If you have the current SYSCPK installed on your system, you do not need to install the Sort/Merge as Tom Armstrong's version 1.01 is already installed on SYSCPK.
The Sort/Merge Utility and installation files are contained in the archive: mvtsort.tgz [MD5: 3ea38c76c3b9ac83b17e647970473221]. Click on the archive name to download the archive to your computer. The archive contains:
a HET tape image (mvtsort.het),
an installation jobstream (mvtsort.jcl),
an installation verification jobstream (sorttest.jcl), and
Tom Armstrong's Application Guide (#APPLPGD.pdf).
Uncompress the archive (use the tar xvzf <archive> command on Linux, or under CYGWIN; or use WinZip or ZipNAll on Windows/??). The tape image should go into your tape image subdirectory, the jobstreams should go into your JCL subdirectory, and the documentation PDF should be stored where you can open and view it as needed.
The Sort/Merge Utility consists of a set of load modules and a set of library routine modules, which are loaded as required during the sort execution. The load modules are contained in the first dataset on the tape image (MVT.SORT.UNLOAD). The loadable modules are contained in the second dataset on the tape image (MVT.SORTLIB.UNLOAD). These two datasets were created by an IEBCOPY unload and the two libraries were unloaded from 3350 DASD (RECFM=U,BLKSIZE=19069).
The restore jobstream uses target dataset names of SYS2.LINKLIB (for the load modules) and SYS1.SORTLIB (for the library modules loaded at runtime). It may be necessary to modify these target datasets for your system.
The sorttest.jcl jobstream performs a simple sort of an instream set of card images and prints the sorted images on the printer. The complete JES2 output for this job may be viewed at sorttest.
After the compiler has been successfully installed and verified, you do not need to retain the installation jobstreams or the tape image on your host computer.
I hope that you have found my instructions useful. If you have questions that I can answer to help expand upon the information I have included here, please don't hesitate to send them to me:
