Syncsort PROCSort is a high-performance sort procedure that provides a direct interface between the SAS® system and Syncsort MFX. Syncsort PROCSort can replace PROC SORT in any SAS job stream, significantly reducing the resources required for sorting within SAS applications. Syncsort PROCSort was formerly known as PROC SYNCSORT and PROC MFX.
Syncsort PROCSort is a functional replacement for the SAS SORT procedure. It functions exactly like PROC SORT.
For complete information concerning the use of PROC SORT, refer to “The SORT Procedure” chapter of the SAS User’s Guide or the SAS Procedures Guide.
Syncsort PROCSort is designed to run transparently. The SAS-provided statement PROC SORT automatically runs Syncsort PROCSort, and no changes to SAS jobs are necessary.
It is important that the region size for the SAS job conform to SAS requirements. If the region is too small, Syncsort MFX issues a message (WER747I) and retries the sort execution. In this situation, performance cannot be optimized. An adequate region size ensures that Syncsort MFX can use its high performance techniques.
When executing Syncsort PROCSort, use SAS language statements and/or options rather than Syncsort MFX control statements or parameters specified in a data set defined by the $ORTPARM DD statement. Use of Syncsort MFX options in $ORTPARM is not compatible with Syncsort PROCSort.
