Explanation: DATASETNAME(dsname), REQUEST, and USER are mutually exclusive, optional parameters requesting a list of selected DFSMShsm requests.
DATASETNAME(dsname) specifies a list of the requests associated with the specified data set name. For dsname, substitute the fully qualified name of the data set for which you want the list of requests.
REQUEST(reqnum) specifies a list of the specified request number for all requests. For reqnum, substitute the DFSMShsm request number.
USER(userid) specifies a list of the requests associated with a specified user. For userid, substitute a 1 to 7 alphanumeric character string for the identification of the particular user.
Defaults: If you specify USER without userid, DFSMShsm lists requests for all users. If you specify REQUEST without reqnum, DFSMShsm lists information for all requests.
