Default VTAM modes

Use the MODEENT macro to enter each default mode into your mode table. When this table is complete, you must assemble and link-edit it into SYS1.VTAMLIB.

The following modes are the default modes:

• SNASVCMG is an optional mode. It is reserved for use by VTAM® for CNOS processing and exists in the VTAM default log mode table. Because SNASVCMG is reserved for use by VTAM, do not enter it as a mode name in the CDB. If you have decided to set up a separate mode table for Db2, you can, if you choose, copy the SNASVCMG mode entry into your Db2 mode table, or just use it as it exists in the ISTINCLM mode table.
• IBMRDB is a recommended mode entry because it is used as a default for DRDA access whenever you do not explicitly assign a mode to a session. It does not exist in the default table; to use it as a default you must add it to your mode table.
