The IBM-supplied file, ISTVTMEU, contains messages for internal and external translation. The user messages defined in ISTVTMEU for internal translation are USSMSG01 through USSMSG13 for USS and IKT00201I through IKT00405I for TSO/VTAM. For example, USS message 1 is defined as follows:

USSMSG01           INVALID &1. COMMAND SYNTAX    &TIME.

You can change the wording of this message to different wording if required. The &1. is an example of a substitution token and is used here to identify where the incorrect command name is to be placed in the message. Additional substitution tokens are &2., &3. and so on. Also, the &TIME., &DATE., &LUNAME., and &NETID. substitution tokens are used for the time, date, LU name, and network ID. If you want to provide USS messages in other languages using MMS, another skeleton file can be created for the required language with the required message text. For example, you could code the following in a new file named ISTVTFRA with the text in French:

USSMSG01           THE SYNTAX FOR COMMAND &1. IS INVALID

Then, if the user specified LANG(FRA) on a USS command, the above message text would be provided in the case of a USS command syntax error. The above message could also be defined as a multiline message, and, when translation occurs, all of the lines in the translated message are written to the LU. There is a 23-line limit on the number of lines in a translated message for USS and an 8-line limit for TSO/VTAM.
