BBjErrorMappingAction

rem ' This sample introduces a RecordSetValue Source mapping

rem ' Mappings can be done with any type of recordset, they are done here
rem ' with MemoryRecordSets so the example stands on it's own.
rem ' Here we map Location, a number to be one of several regions.
rem '0= NORTH, 1= SOUTH, 2 = WEST, 3 = EAST
rem ' we specify an ErrorMappingAction because anything other than these 4 values is exceptional
rem ' see also the FormatMappingAction.
