Programs running in a started task procedure address space start with a clean ISPF environment. To ensure that no ChangeMan ISPF tables are left open in a user’s address space, a TBEND is issued for each ISPF table that was created during the session.

These TBENDs occur when you exit from a client ChangeMan ZMF session in an ISPF environment. ChangeMan knows which tables to TBEND by maintaining another ISPF table called CMNTBN. CMNTBN contains a list of all ISPF tables created during the ChangeMan session.

Table CMNTBN may help you when you are debugging under ISPF dialog test.
