Each individual user of the dump viewer on TSO/ISPF gets a unique profile member in the ISPF profile data set. The profile member contains general options for the user, such as PF key settings. The profile member also contains up to twenty entries (called slots) used to store state information about dump data sets that were viewed. Each slot is associated with a dump by the name of the reports data set.
When a user selects a dump data set for viewing for the first time, a new slot is allocated for that dump data set in the user's profile. Each user can keep profile information for up to 20 dumps concurrently. If all of the slots are used, the one with the oldest date of last reference is recycled.
A dump slot in the profile contains information required to restore the viewing environment to its most recent state. The state information includes:
When a viewing session is ended, information is stored in the appropriate profile slot. When the same dump is selected again for viewing, the last viewing state is restored automatically.
The profile member also contains up to 20 slots for electronic notepad data. These slots are separate from the state information but are managed in exactly the same way. Each individual user can keep notes for up to 20 dumps, and the slots are associated with the dump by the dsname of the reports data set.
Both state data and notes data for a dump are limited to a maximum length of 32 KB. Once this limit is reached, no additional data can be stored in the profile slot.
