Upda te Files Files for System Updates
Each of the components of Ve/370 has a unique character module
identifier, which is used to name the component's modules. These
component identifiers are also used to name the files used to update the
components. The identifiers are: CP CMS RSCS IPCS DMK Df!S DMT DMM The default CMS filetypes are used to identify the source, object
code, module files and libraries associated with each component. These
filetypes are: ASSEMBLE TEXT TXTAP MODULE PIACLIB of Source File Object deck (relocatable) Object deck with Attached Processor Support (relocatable)
Nonrelocatable object code Macro or copy library
Two of the update procedures, VPIFPIAC and VMFASM, use the CMS UPDATE command to update macro libraries and source files. Since the updates
that are applied are multilevel updates, there are control files (with a
filetype of CNTRl) and auxiliary control files, (with filetypes of AUXxxxxx) as well as the actual update files (consisting of UPDATE control statements and new source records). These files may have the
following generic filetypes: CNTRL AUXxxxxx UPDTxxxx anything lile Control file
Auxiliary control file

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
