The Navy uses a modified system message catalog (set 2, messages 6005 and
6006). By putting the logon message in the message catalog they are
guaranteed
that the message will be displayed even if the operator changes the WELCOME
message. Also, while the Navy's login message is quite long (standard DOD
warning), the message catalog accomodates it quite well. To give you some
idea
of its size, I've displayed the login message with following WELCOME message
(begins "Notice:") below.
CDA9:Hello Manager/xxxxxxxx.Sys/xxxxxxxx

CDA9[1]:
------------------
When modifying the system message catalog there are a couple of gotcha's to be
aware of.
1) Remember to use the proper continuation characters.
2) Use a record size of 72 bytes. 80 sometimes works, but sometimes it
doesn't.
3) Don't put a continuation character ("&" or "%") in column 72 - it
almost always causes a problem.
4) Some existing messages will cause you grief when you try to run MAKECAT
against the catalog file. Generally, the messages MAKECAT will object
to are those in which there is a continuation line which begins with
a number.
5) You must use MAKECAT,BUILD to install the catalog, then make a new
SLT.
6) Before running MAKECAT,BUILD, make sure there are no errors in the
new catalog. Due to a bug in MPE/iX, you only get one attempt with
MAKECAT,BUILD without having to reboot the system.
With dozens of systems, the Navy's system message catalogs have several other
messages changed in addition to the login messages shown above. The messages
are modified to include the system name so that users connected to several
systems at a time can tell where they are and in the case of TELL and WARN
messages, which system the message came from. Below is a portion of the
modified catalog showing most of the messages we modified. Following those
messages is a listing of the login and logout messages we replaced showing the
original messages which we commented out and the new messages (with
continuation characters) we inserted.
