Specifies the version of the messages to use for those messages listed in z/OS Communications Server: SNA Messages. If the MSGLVL operand is specified on the USSMSG macroinstruction, it overrides the value specified on the MSGLEVEL start option.

Note: You can abbreviate the MSGLEVEL start option to MSGLVL.
You can change the value of MSGLEVEL with the MODIFY VTAMOPTS command while VTAM® is running.
MSGLEVEL=BASE
Specifies that for all messages, except those that are coded otherwise in the USS table, VTAM issues the pre-V4R1 message that this message number replaces.

See z/OS Communications Server: SNA Messages for a list of messages replaced by a new message or a message group.

If you specify MSGLEVEL=BASE and there are duplicate names in your SNA interconnected networks, you might not know which resource the message applies to because the message does not use a network-qualified name.

MSGLEVEL=V4R1
Specifies that VTAM issues the V4R1 message or messages, except for those that are coded otherwise in the USS table.

See z/OS Communications Server: SNA Messages for a list of messages replaced by a V4R1 message or message group.

MSGLEVEL=V4R2
Specifies that VTAM issues the V4R2 message or messages, except for those that are coded otherwise in the USS table.

See z/OS Communications Server: SNA Messages for a list of messages replaced by a V4R2 message or message group.

MSGLEVEL=V4R3
Specifies that VTAM issues the V4R3 message or messages, except for those that are coded otherwise in the USS table.

Seez/OS Communications Server: SNA Messages for a list of messages replaced by a V4R3 message or message group.

MSGLEVEL=V4R4
Specifies that VTAM issues the V4R4 message or messages, except for those that are coded otherwise in the USS table.

See z/OS Communications Server: SNA Messages for a list of messages replaced by a V4R4 message or message group.

MSGLEVEL=CS390
Specifies that VTAM issues the z/OS® Communications Server message or messages, except for those that are coded otherwise in the USS table.

See z/OS Communications Server: SNA Messages for a list of messages replaced by a z/OS Communications Server message or message group.
