Restriction: RANDOM must follow a DDNAME level selector. RANDOM can be used for applications that perform mostly RANDOM processing, but specify DYNAMIC in the file definition.
Selecting DDNAME and specifying RANDOM forces the dynamic buffering routines to select buffers as if RANDOM had been specified in the file definition instead of DYNAMIC. This results in more index buffers, which should improve random accesses.
There are no operands for RANDOM.
