Modifying Data Sources With MODIFY

Topics:

 

These topics describe how to maintain FOCUS-supported data sources using the FOCUS MODIFY facility. MODIFY requests can add, update, and delete data from FOCUS data sources, including HOLD files converted to FOCUS format (see the Creating Reports manual).

The MODIFY facility is also used to maintain data in relational structures, Adabas data sources, and VSAM data sources. See documentation for specific data adapters for details about using MODIFY in those environments.

MODIFY can also be used to load fixed format sequential data sources that consist of a single segment. Data is loaded in the order in which it is input. Update and delete operations are not supported with this type of data source. If the file already exists, new data is loaded at the end. In order to append data to a sequential data source with HiperFOCUS ON, the record format must be fixed.
