USS messages sent to terminal users

The session-level USS table contains definitions for USS messages that are sent to terminal users. These messages consist of USSMSG00 through USSMSG14. VTAM® issues these messages in response to commands sent by logical units (for example, a character-coded logon or logoff command).

The USS messages are described in the following section as they are defined in the IBM-supplied session-level USS table, ISTINCDT.

You can also define two messages of your own.

USSMSG00: The text you define for this message is issued after VTAM has accepted a USS command from a terminal user.
USSMSG10: The text you define for this message is issued after a logical unit is activated.

Note: For a BSC 3275 terminal, the following messages are not printed on the attached terminal. The message only appears on a 3275 display screen.
