The following factors affect code path length when data set separation is requested:

• The number of data set names listed in the data set separation profile. (SMS must scan the profile to determine whether data set separation processing is needed for the current allocation.)
• The number of data set names listed within a data set group when data set separation is performed for that group
• The use of wildcard characters in the separation data set names
• The number of volumes that are eligible for selection.
