How does the BEGRNG - NXTRNG work?

The BEGRNG/NXTRNG commands read records in the order of the index that is part of the API. So, for example, if using 850-FIND-BEGRNG-APPSET3, it is using index APPSET3 to return the records. The way it works: You fill as many of the DB- fields in the index as possible, starting from the "top" of the list of fields, and then specify the last field you are filling by moving XXXSETY-FIELD-NAME (e.g. APPSET3-REC-STATUS) to WS-DB-BEG-RNG. So using APPSET3 as the example, you might more a value "XYZ" to DB-PAY-GROUP, 3 to DB-REC-STATUS, and APPSET3-REC-STATUS to WS-DB-BEG-RNG. The 850-FIND-BEGRNG-APPSET3 will return the first APPAYMENT record matching APP-PAY-GROUP = "XYZ" and APP-REC-STATUS = 3. Then calling 860-FIND-NXTRNG-APPSET3 until APPAYMENT-NOTFOUND will return all other APPAYMENT records matching APP-PAY-GROUP = "XYZ" and APP-REC-STATUS = 3. The records are returned in the order of the index APPSET3. The asterisk means that the field is stored in descending order.
