Examples

Populates message database or generate message constant sources in C, Fortran, and BASIC

$ show log sys$message "SYS$MESSAGE" = "SYS$SYSROOT:[message]"
The messages can be viewed quickly using VX/DCL, though the records contain some binary data, using:
$ type/page sys$message:messages.sys
Where messages.sys is an indexed file with data (.dat) and indices (.idx) in separate files.
Depending on your config options you may see this as either upper or lower case, and one or two files.
The actual files are shown below with the default symbolic links to support either case mapping.

$ls -l $VXREL/message total 1144 -rw-rw-r-- 1 JDOE s7dev 16 Mar 8 21:33 messages.sys.dat -> MESSAGES.SYS.dat -rw-rw-r-- 1 JDOE s7dev 1105585 Mar 8 21:33 MESSAGES.SYS.dat -rw-rw-r-- 1 JDOE s7dev 16 Mar 8 21:33 messages.sys.idx -> MESSAGES.SYS.idx -rw-rw-r-- 1 JDOE s7dev 65536 Mar 8 21:33 MESSAGES.SYS.idx
For example, this command in our makefiles populates the standard messages file distributed with VX/RT
$(VXREL)/message/MESSAGES.SYS.dat: $(BINDIR)/msg @$(BINDIR)/msg < messages.msg
