ISPF profile
When you access the ISPF interface for the first time, the MainView Batch Optimizer dialog creates member BSSBPROF in your ISPF profile data set.
This member contains information about your dialog sessions and some of the input field values from your previous session.
For example, the dialog retains the name of the most recently accessed control data set. If you modified MainView Batch Optimizer dialog keylists, BSSBPROF also contains a copy of member BSSBKEYS from ISPTLIB with your modifications. Each time you access the MainView Batch Optimizer user interface, it restores values in the data entry and choice entry fields from information saved in the BSSBPROF member. If you delete member BSSBPROF from your profile data set, the MainView Batch Optimizer user interface creates a new one for you with MainView Batch Optimizer default values.
