VERIFY: Verifying data before changing It

Explanation: VERIFY(address [data | BITS(bits)]) is an optional parameter requesting that DFSMShsm verify the current data before it makes the change. If the data does not match, DFSMShsm rejects the change.

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, you 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). The leading period is still required.

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

For data, specify the data that you want DFSMShsm to verify. You can verify up to 256 bytes of data.

For bits, substitute an eight-character string specifying which bit or bits are to be turned on or off. A period (.) means do not test, a 1 means test bit for on, and a 0 means test bit for off. For example,

1.0.....

means test bit 0 for on, test bit 2 for off, and do not test the remaining bits.

Abbreviations: None.

Defaults: None.

Note: You cannot use indirect addressing, registers, and variable names with the PATCH command.
