You can specify a management class name or vital record specification management value in a data set name vital record specification. A management class name or management value can be one to eight alphanumeric characters, beginning with an alphabetic character, and must follow standard z/OS® data set naming conventions. This name must be a single qualifier, but can include mask characters to create a single generic qualifier covering multiple management classes or management values. To create a generic management class name or management value, use an * to match any character string and % to match any one character. For example, you can define the management class name MC123* for all data sets with a management class starting with the character MC123.
