Message Records You can create your own user or system message records with the SNAXUTL ADD
ESSMSG command. The message text can consist of either alphabetic or single-byte
Katakana characters.
Records for User Messages
To add a user message to the ESS table, you must first place its character-coded name
in the message-name field of the ADD ESSMSG command. You can name a user
message whatever you wish, as long as its name does not duplicate that of a system
message (for information on system messages, see “Records for System Messages”
below).
You place the message text itself in the MSGTEXT operand. This text, enclosed in
quotation marks, can be from 1 to 4042 bytes long.
Whenever the terminal user enters the name of a user message, that message is
displayed on the screen. You can create as many such messages as you wish.
Records for System Messages
Tandem provides you with a number of system messages in an edit command file
called $SYSTEM.SNAX.SYSMSG (for a list of these messages, see Appendix B).
Before you run SNAXUTL, you can change the text of any system message by editing
the command file. However, after you have made these messages part of an ESS table
source file, you can change their text only in the following ways:
1. By purging the table source file and table object file and then running SNAXUTL
with an edited version of the original command file
2. By creating and running another command file that uses the SNAXUTL DELETE
and ADD commands to delete and add message records
A system-message name must begin with the character S, followed by four numeric
digits. LUNS displays system messages when an error occurs. The terminal user can
also display any system message by entering its system-message name.
