MPE/iX offers three KSAM file formats: CM KSAM, KSAM XL and KSAM64. CM KSAM is the two-file KSAM structure used on MPE V/E systems.

KSAM XL and KSAM64, single-file KSAM structures, are used only on MPE/iX systems. KSAM XL and KSAM64 files offer a more convenient single-file format.

Programs running in CM or NM can access any type of KSAM file. Use the FCOPY utility to migrate data and rebuild indexes from one KSAM file format to another.

NOTE: RPG Programmers:

Record-level locking cannot be used for any type of KSAM file on MPE/iX.
