Pointer/Set Relationship Statement

Pointer/set relationship statements provide CA IDMS DML with information about the pointers established for each record type that is to be passed from the database to the user work area. One pointer/set relationship statement must exist for each pointer that is to be passed for the record type described in the preceding file/record type description statement.

IMBS

Constant; Code anywhere after column one.

pointer-number

Specifies the two-digit number corresponding to the sequential number in the set identification statement (see above) for the set to which the pointer links the record.

pointer-type

Specifies the type of pointer, as follows:

• N— Next pointer
• P— Prior pointer
• O— Owner pointer
• X— Dummy pointer; causes the constant END to be moved to the specified pointer position in the simulated DBOMP record

pointer-displacement-number

Specifies the displacement of the pointer in the DBOMP logical record, where the record begins at byte 1.
