HP RPG/XL Utilities-Part 1 XSORT

Work Space 

XSORT tells SORT how much work space will be required for performing the
actual sort.  For single-file input from disk, it determines the space
needed to sort by the number of records in the input file.  You can
directly supply this number by specifying the "maximum numbers of records
to be sorted", using the S Option (See Section 4).  This must be done in
the following two cases:

 *  Single-file non-disk input--including $STDIN.

 *  Multiple-file input.

If only a small percentage of the records from a single-file sort are
being selected and sorted, XSORT will make more efficient use of
resources if a reasonably accurate "maximum number of records to be
sorted" is specified using the S Option.
