When an operator issues a CLIST command on the operator console we get this error:
R 348,CVON
DC066001 OPERATOR COMMAND NOT RECOGNIZED
Release : 19.0
Component : CA IDMS/DB
If not using one of the documented operator commands you have to prefix the reply with 99 to indicate you are executing a task code.
To execute a CLIST from the console in z/OS, reply to the outstanding reply using the following syntax:
R nn, 99CLIST clist_name
See the CA IDMS documentation on Operator console command syntax
