User Guide for DFSORT PTFs UI35396 and UI35397

z/OS DFSORT V2R1 PTF UI35396 and z/OS DFSORT V2R2 PTF UI35397, first available in March, 2016, provides important enhancements to DFSORT exit processing of E15/E35 exits to support the transfer of blocks of records between DFSORT and E15/E35 exits. With this new support for inserting blocks of records it will expand the functionality of the existing E15/E35 exits which will significantly reduce the number of calls of the E15/E35 exits, and will reduce the transfer of records between user's storage and DFSORT storage. Further-more, the new E15/E35 block support does not affect the existing support of single record interface.
