We have kept IBM supplied tables in VTAMLIB, that includes VTAM's default logmode table ISTINCLM. Do XCOM LOGMODE entries need to be included with ISTINCLM and reassemble and linked into new table?
It is advised that the XCOM LOGMODE table entries be kept with IBM's ISTINCLM in the VTAMLIB library for that system. For additional information please refer Define the Logon Mode Table Entries
