IBM SC33-1683-02 VTAM MODEENT macro operands

VTAM MODEENT macro operands

Table41 VTAM LOGON mode table entry for each TYPETERM you might deﬁne.

Youshould have reached this table by looking up the TYPETERM device types in

Table40 on page 768.

Look down the left hand side of the table for the reference number (RN) that

brought you here from Table40 on page 768. When you ﬁnd it, look across to the

middle column. This shows the macro operands that affect the way CICS handles

automatic installation. YourMODEENT macro entries for devices to be installed

must match what is speciﬁed there. Any MODEENT macro entries not shown in the

table, such as PSERVIC for some reference numbers, are not tested by CICS. Any

bit settings that do not matter to CICS during bind analysis for autoinstalled

terminals appear as periods (.).

Note: Some ﬁelds in the PSERVIC data for LUTYPE0, LUTYPE2, and LUTYPE3

devices have values that depend on the ALTSCREENand DEFSCREEN

characteristics of the device. For this reason, you have to consult “PSERVIC

screen size values for LUTYPEx devices” on page775 to ﬁnd out the values

you need to specify instead of aaaaaaaa, bbbbbbbb, cccccccc, dddddddd,

and eeeeeeee.

The right-hand column in the table names entries in the CICS-supplied LOGON

mode table that could meet your needs. The CICS-supplied table is called

ISTINCLM. For further VTAM information, refer to
