Update Files is used for CMS source updates. Its contents are: TEXT MACS CMSLIB OSMACRO TEXT AUXRnO is used for CMS copy and macro updates. Its contents are: TEXT MACS TEXT AUXftnO is used for RSCS source, copy, and macro updates. Its
contents are: TEXT MACS DMTLOC DMTMAC TEXT AUXRnO QftMRnO is used for IPCS source, copy, and macro updates. Its
contents are: 'fI1i!I'fl nMKMAC TEXT AUXRnO is used for assembling the NCPDUMP source. Its contents
are: TEXT MACS OSftACRO DMKMAC CMSLIB TEXT AUXRnO All auxiliary control files distributed by IBM have the filetype AUXRNO (or AUXMnO for CMS MACLIB changes). When an update is issued for
a module, an auxiliary control file is also distributed. For example,
if an update is sent for DMKCFM then the file DMKCFM AUXRnO is also
distributed. This file, DMKCFM AUXRnO, lists the updates to be applied
to the CP module DMKCFM. All of the the update files distributed by VM/370 are assigned
filetypes as follows:
nnnnnxx
Z indicates a Release 5 update. M indicates a CMS macro update.
R indicates a Release 6 update.
nnnnn is an APAR or PTF number.
xx is the 2-character component identifier (DK, DS, DT, or DM). For example, the code and updates to answer APAR VM12765 against the
Release 6 level of CP module DMKCFft are contained in the file DMKCFM R12765DK. The file DMKCFM AUXRnO contains the entry:
R12765DK - COMMENT DESCRIBING FIX 328 IBM VM/370 Planning and System Generation Guide

Page of GC20-1801-10 As Updated April 1, 1981 by TNL GN25-0837 Update Files
When you create files for local updates of VM/370 modules, you should
create a local control file, consistinq of the appropriate VK/370 CNTRL
file with an entry for your local MACLIB and AUX file. For example, the
file CPLCL CNTRL may contain: TEXT LCLLIB DHKMAC CMSLIB OSMACRO LeL AUXLCL TEXT AUXRnO The AUXRnO control file should be last in the control file, so that the IBM updates are applied first. (Remember that the UPDATE command, when
applying multilevel updates, reads from the bottom of the control file.)
Text files must have a filetype of TEXT. For example, after you have
updated an object module using VMFASM, the most recent object file has a
filetype such as TXTLOCAL. To use that text file here, you must rename
it to a filetype of TEXT. If there is currently a text file on the
system disk, you may rename it too, so that your updated text file (which may reside on another disk) is the one that is loaded.
