The ACS routines assigned a null Storage Class as expected, thus making the data set non-SMS managed.

Figure 123 on page 189 shows the same data set name pattern tested against the updated SCDS. As can be seen on this occasion, the data set acquires a valid Storage Class and is therefore eligible for SMS management. Valid Management Class and Storage Group attributes are also assigned:
