Allocating space for sort files
If you use NOFASTSRT or an input procedure,
DFSORT does not know the size of the file that you are sorting. This
can lead to an out-of-space condition when you sort large files or
to overallocation of resources when you sort small files.
About this task
If this occurs, you can use the SORT-FILE-SIZE special
register to help DFSORT determine the amount of resource (for example,
workspace or hiperspace) needed for the sort. Set SORT-FILE-SIZE to
a reasonable estimate of the number of input records. This value is
passed to DFSORT as its FILSZ=En value.
