OUTFIL

OUTFIL is a control statement that allows you to create one or more output data sets for a sort, copy, or merge application with only one pass over an input data set. You can use multiple OUTFIL statements, with each statement specifying the OUTFIL processing to be performed for one or more output data sets.

With a single pass over an input data set, OUTFIL can create one or more:

Output data sets containing unedited or edited records
Output data sets containing different ranges, samples, or subsets of records. Those records that are not selected for any subset can be saved in another output data set.
Reports containing different header records, detail records and trailer records.
FB output data sets from a VB input data set.
VB output data sets from an FB input data set.

OUTFIL has many additional features as well; see z/OS DFSORT Application Programming Guide for complete details on all of the tasks you can perform with OUTFIL.
