64-bit support

Eligible user programs and exits can now be written to:
  • Call DFSORT from a program in 64-bit addressing mode (AMODE 64) using a new 64-bit parameter list and the entry name ICEMAN64 or SORT64
  • Use DFSORT E15, E35 and E32 exits running in 64-bit addressing mode (AMODE 64)
  • Pass 64-bit addressed records to DFSORT using new 64-bit parameter lists for E15, E32 and E35 exits.
