Default contents of summary dumps in ABEND dumps

If only a summary dump is requested, as in a SYSUDUMP dump that is not customized, the summary information is together, because it forms the entire dump. When a summary dump is combined with other dump options, the summary dump information is scattered throughout the dump. In Table 1, an S indicates that a summary dump is available with the dump type.

PSW (program status word) at entry to ABEND, that is, when the dump was requested. The PSW includes the instruction length code and the interrupt code for the failing instruction. S S S

Storage: 4 kilobytes before and 4 kilobytes after the addresses in the PSW and the registers.

The dump shows, by ascending address, only the storage that the user is authorized to access. Duplicate addresses are removed.

TCB summary: Information from the task control blocks (TCB) in the address space being dumped S S  
Virtual storage map: The subpools in the address space being dumped:
