TEST—WHERE subcommand

Use the WHERE subcommand to obtain:

An absolute address
The name of a module and CSECT
A relative offset within the CSECT
The address of the TCB for the specified address.

You can also use the WHERE subcommand to obtain the absolute address serving as the starting or base location for the symbolic and relative addresses in the program. Alternately, you can obtain the absolute address of an entry point in a particular module or control section (CSECT). If you do not specify any operands for the WHERE subcommand, you receive the address of the next executable instruction, the related load module and CSECT names, and the hexadecimal offset.

Note: After an abend outside the home address space, do not specify WHERE without operands. The home and primary address space identifiers (ASIDs) are different after an abend, resulting in an instruction address which TEST cannot access.
