The old retention rules specified data sets by how they where qualified. The following Is how they correspond with the pattern masking type:
Fully qualified data set name. This is the same as type “0”. The DSN of the retention rule must match the entire 44 character data set name.
Partially qualified data set name. This is the same as type “5”. The first 1 to 43 characters of the data set name must match the first character of the pattern. The pattern matching character is a “-“ instead of a “/”. Type “5” pattern masking also allows you to specify a jobname which this does not.
IBM-qualified data set name. This is also the same as type “5” but a “.” Must proceed the “-“ pattern masking character
