In this example, three tape volumes 001200, 001201, and 001202 are to be rekeyed with the same key labels specified for the first REKEY control statement with NUMBTAPE specified. The second control statement specifies one tape SL8000 to be rekeyed with different key labels. Note, that KEYLABL2 and its associated KEYENCD2 are omitted, thus the same key label and encoding mechanism values specified for the KEYLABL1 and the KEYENCD1 keywords are used for both key labels.
