Data Set Groups

A data set group is a collection of data sets for which stacking statements can be specified.

• A group name is assigned to each data set.
• Each group name is associated with a set of stacking statements that determine where (and with which data sets) members of the data set group can be stacked.
• To apply a stacking statement to a data set, the data set must first be associated with a data set group.
• Group names are re-assigned each time the CTTSBD utility is run.

All statements specified for data set groups are applied using input data set names. Prefixes and/or suffixes (OUTPREF and OUTSUFF parameters) added to data set names do not affect application of data set group stacking statements during the current run of the utility. However, these prefixes may affect future runs of the utility.
