z/OS data set naming rules in Rational Team Concert for System z

The following z/OS® data set naming rules must be observed when you allocate a data set or create a new data set member. Use the data set definition editor to make these specifications.
Note: The Data Set Name field in the data set editor can be blank, or the name can begin with &&.
