Retrieving Master Data Using a Key Value
This paragraph implements the GET-PRODUCT-RECORD routine of the sample program. The
calculated access is achieved by a call to DBGET in mode 7. The exceptional condition in this
routine is indicated by status 17 for search values which do not have any corresponding
entries. Error trapping calls 1100-GET-ERROR-AND-EXPLAIN upon detection of a
non-exceptional condition.
