Function

The purpose of the service procedure is to provide the generator with data to be used to generate a report. The service procedure must know the database from which the data is to be retrieved and the format of the data. The name of the service procedure is defined in the table entry for the report application to which the report belongs and is executed by the generator.

Functions of the Service Procedure are as follows:

• Initialization processing, for example, open files, search database (&NDBSCAN)
• To get the next record to be processed (that is, set the data fields)
• To get the value of the sort fields for the next record to be processed
• Termination processing, for example, close files
