Utility Statements › RESTRUCTURE › Callable Restructure Utility › Parameters

Parameters

parm-1

The address of the FSR (SR51) control block from the "old"subschema. This block should describe the record as it exists before the restructure takes place.

parm-2

The address of the IDMSRSTT base restructuring table that describes the changes being made to the database record. This table is generated from the IDMSRSTT macro. (See Appendix B.) The table is searched for the RREC block that matches the FSR name passed in parm-1.

- or -

The address of the RREC control block in the IDMSRSTT table. (No search is done.)

parm-3

The address of the data record to be restructured. Only the data should be passed, not pointers or internal fields.

parm-4

The address of a buffer where the restructured record will be returned. It should be large enough to hold the maximum size of the record being restructured as described in the 'new' subschema.

On exit:

• R0 contains the address of the IDMSRSTT RREC block for the record just restructured, if found.
• R15 contains one of the following return codes:
  • 0: Call successful - The output buffer contains the restructured record.
  • 4: FIELD=ALL was specified for the record in the IDMSRSTT table. There were no changes to the data. The output buffer does not contain a copy of the record; the caller should use the input record image.
  • 8: The record was not found in the IDMSRSTT table.
