TCT

The TCT system initialization parameter specifies which terminal control table, if any, is to be loaded.

TCT={NO|xx|YES}

For guidance about coding the macros for this table, see TCT - terminal control table .

If you reassemble the TCT after starting CICS, any changes are applied when you next start CICS, even if it is a warm or emergency startup.

If you have z/OS Communications Server-connected terminals only, you can specify TCT=NO. If you do this, a dummy TCT called DFHTCTDY, is loaded during system initialization. For more information about DFHTCTDY, see The dummy TCT, DFHTCTDY. If you code TCT=NO, you must specify a CSD group list in the GRPLIST parameter.
