 UNARC does a LISTCAT VOLUME on datasets with your userid as a high level node.
 It then creates a batch job which will access each one of those datasets (an
 IDCAMS PRINT with a COUNT(1)).  Because they are archived, tape mounts will
 automatically be issued for each dataset.  When the JCL is created, you are
 taken into an edit session on the JCL.  If you do not wish to unarchive a given
 dataset, just delete that line of IDCAMS SYSIN code before you submit the job
 (the job is not submitted for you).
