Dumping storage in a data space

Use the following macros to dump data space storage.

Use the DSPSTOR parameter on the SNAPX macro to dump storage from any data space that the caller has addressability to, providing the program also has a TCB key (for SCOPE=SINGLE and SCOPE=ALL data spaces) or a PSW key (for a SCOPE=COMMON data space) that matches the storage key of the data space.
Use the DUMPOPX parameters on the ABEND macro and the SETRP macro with the list form of the SNAPX macro to dump data space storage.
Use the LISTD and SUMLSTL parameters on the SDUMPX macro to dump certain ranges of data space storage:
- LISTD identifies (by STOKEN) the data space that contains storage to be added to the main part of the dump.
- SUMLSTL identifies (by ALET) the data space that contains the storage to be added to the summary part of the dump.
