READ.ME
This directory contains the source files, include files, and command files needed to build the PL/M-VAX runtime library (including the UDI routines), and the configuration macro library.
The *.PLM, *.MAR, and *.FOR files are source files. The *.LIT, *.DEF, EXCEPT.FOR, RMSDEF.FOR, IODEF.FOR, and XQCOMMON.FOR files are include files. (RMSDEF.FOR and IODEF.FOR are copies of parameter definition files from SYS$LIBRARY. Apparently these files are not present in all VMS systems.)
UDIMSGS.MSG is the source file for the UDI message facility.
LOGNAMES.COM is a command file containing logical name assignments used by other command files in this directory. LOGNAMES.COM should be edited to reflect the directory names in use on your system. Any command file which makes use of system-dependent logical name assignments will contain a call to LOGNAMES.COM, so LOGNAMES.COM should be the only command file requiring editing.
PLMRUN.BLD is a command file to build the PLMRUN.OLB library from scratch. XQIO.BLD is a command file to rebuild just the XQIO package.
PLMMAC.BLD is a command file to build the PLMMAC.MLB configuration macro library from scratch.
DM.MAR is a source file used to produce the dummy (null) object file DM.OBJ which is referenced by various *.LNK command files to satisfy the VMS linker's need for an object file specification in the CLUSTER command. DM.COM is a command file used to assemble DM.MAR.
VMSRTL.V23 is version 2.3 of the VMS shared runtime library. Various *.LNK command files reference this copy (rather than the currently installed shared library) in order to produce executable images which will run under VMS 2.3 (and later).
MAKETAPE.COM is the command file used to write the contents of this directory to mag tape.
