Progress 4GL Reference

RETURN-VALUE attribute

The value returned from user-defined functions, attributes, and methods.

Note: Supported only if the CALL-TYPE attribute is set to FUNCTION-CALL-TYPE or GET-ATTR-CALL-TYPE.

Data type: The value of the RETURN-VALUE-DATA-TYPE attribute.

Access: Readable

Applies to: CALL object handle

The default is the Unknown value (?).

If you set the RETURN-VALUE-DATA-TYPE attribute to a particular data type before executing INVOKE( ), the value returned is converted to that data type.

If RETURN-VALUE-DATA-TYPE is set to its default value or to the expected data type, when the dynamic invoke returns, the value returned by the user-defined function or attribute is not converted.
