Address: Specifying the location to change

Explanation: address is a required positional parameter specifying where you want the DFSMShsm address space changed.

For address, substitute the absolute address or the qualified address of the location you want to change. Although the addresses contain hexadecimal digits, you do not represent them in the form X'nn'. Instead, enter them in the following manner:

Enter an absolute address as one to eight hexadecimal digits followed by a period (hhhhhhhh.).
Enter a qualified address as a DFSMShsm load module name, followed by a period, a CSECT name, a period, a plus sign, and one to six hexadecimal digits (loadmodulename.csectname.+hhhhhh). Because ARCCTL is the only load module that can be displayed, the load name of ARCCTL is always used as the load module name if you supply only the CSECT name and offset (.csectname.+hhhhhh).
Note: The leading period is still required.

The PATCH command considers the .MVT. control block identifier to be a valid control section (CSECT) name.

Abbreviations: None.

Defaults: None.

Note:

Because address is a required positional parameter, you must specify it immediately after the command name.
You cannot use indirect addressing, registers, expressions, and variable names with the PATCH command.
You cannot patch addresses in a DFSMShsm secondary address space.
