and indeed, changing that to the standard

       01  Z01-SHMKEY.
         05 Z01-SHMKEY-ENV        PIC  X(06).
       01  Z01-SHMKEY-RED REDEFINES Z01-SHMKEY.
        03 filler OCCURS 6                     INDEXED BY Z01-IND.
         05 Z01-BYTE               PIC  99 COMP.

does compile


My suggestion would be to:

* ensure the diagnostic points to the data item (it _seems_ to point to end of
storage definition)
* mid-term: support that nonstandard option
* short-term: raise an error message on 01 OCCURS (or, if this is supposed to
commonly work: on OCCURS with REDEFINES on the same data item)
