Data Type Casting Rules for Progress 4GL Calls to Web Services

This appendix describes how OpenEdge casts between the following 4GL data types and XML Schema data types in parameters passed to Web services called from the 4GL. Any casting between a 4GL type and an unsupported XML Schema type or an invalid match between a 4GL type and a supported XML Schema type raises a 4GL run-time error, as detailed in the following sections:

CHARACTER or LONGCHAR
DATE
DATETIME
DATETIME-TZ
DECIMAL
INTEGER
LOGICAL
MEMPTR or RAW
Note: The following tables describe data transformations for the 4GL INPUT and OUTPUT parameter modes. The INPUT-OUTPUT parameter mode behaves in the same manner.
