CA SymDump System provides the following built-in symbols for each dump:

PSW

The PSW at the time the dump was captured.

CURRTCB

The address of the TCB which requested the dump.

R0 thru R15

The general purpose registers at the time of the dump.

Examples

Symbols are used in the following examples:

To disassemble the instruction at the PSW address at the time of the dump:

DISASSEM PSW
or
DISASSEM PSW-2

To map the TCB at the time of the dump:

MAP CURRTCB

Note: Most OS control blocks can be mapped using Auto-Mapping and therefore do not require a map name.

MAP R13+4?,SAVEAREA
