By "turn off cics screen" do you mean the CICS logon logo when the sessions starts?
If it is, you can get rid of the CICS screen by changing the GMTRAN= parm in the SYSIN SIT overide.
The default is GMTRAN=CSGM. If you change that too CESN, the user will get the GMTEXT= string and the RACF SIGNON screen (OR other ACF depending on your installation).

You can also write your own program and maps to be executed and the specify that transaction ID on the GMTRAN= parm.

When I say turn off cics screen. They want to turn off conversations. I have about 100
conversations to turn off. I would think this would be a table update. However, cannot
find any tables for the conversations? Any suggestions?

Also another question?

Is this correct?

Type for cobol program

COBBD = BATCH AND DB2

COBC = CICS AND NO DB2

COBCD = CICS AND DB2

Thanks

turn off conversations. do you mean cancel conversational transactions ?

if so, you can manual cancel/purge via CEMT I TASK screen

please explain what you are specifically trying to accomplish?

Yes, I want to cancel conversation transactions so when the user types
in a conversation it will not take him to the screen.

So do I (cemt i task(XXX) XXX= 3 byte conversation?

Please walk me through this.

Thank You!

based on your last response, sounds more like you want to prevent
user from accessing a CICS transaction

Have your CICS systems programmer remove the transaction ids' from
the CICS RDO group or disbale them

or
if you have RACF or ACF2, you could change the security access level.
