VERIFY: Verify that a field in a CDS record matches the given data

Explanation: VERIFY (offset[data| BITS(bits)]) | is an optional parameter used to confirm that the data in the control data set record matches the specified data. If VERIFY is specified, the requested function can only be performed if the VERIFY is successful. VERIFY should always be used with the PATCH parameter: If the verify fails, the patch is not performed.

For offset, specify a decimal value anywhere from zero up to a number equal to the length of your CDS record, or an equivalent hexadecimal value, that represents the variable data portion of the record you want to check. If the ENTRY parameter is used, offset applies to the particular entry in the record and not to the record itself. Hexadecimal characters must be in the form X'n'.

For data, substitute the data you want checked. You can enter the data as hexadecimal characters or alphameric characters and $, #, or @. You can verify up to 256 bytes of data.

For bits, substitute an eight-character string specifying which bit or bits you want to test for on/off. A period (.) means do not test, a 1 means to verify if the bit is on, and a 0 means to verify if the bit is off. For example,

           1.0.....

means verify if bit 0 is on and bit 2 is off.

Abbreviations: None.

Defaults: If you do not specify one of the optional parameters of FIXCDS, the default is DISPLAY.

Note:

VERIFY is not required when you specify the PATCH parameter, but its use is recommended.
VERIFY can be used alone, without the PATCH parameter.
