For the E35 exit, DFSORT supports both a 32-bit parameter list and a 64-bit parameter list. If you want DFSORT to use the 64-bit parameter list for your E35, you must call DFSORT with the 64-bit invocation list, and:

• use a MODS control statement for E35 with the N64 parameter or
• set on bit 5 of byte 9 in the 64-bit invocation list

Otherwise, DFSORT will use the 32-bit parameter list for your E35.
