ParseReturnValue Attribute
Data Type: integer
4GL Access: RW
Specifies the return value of the invoked parsing method, XMLDocument.ParseString() method (see ParseString Method) or XMLDocument.ParseURL() method (see ParseURL Method), when parsing has been aborted.
If any called 4GL handler procedure aborts parsing by returning ER_FAIL, the ParseReturnValue setting is returned back to caller of the XMLDocument parsing method.
If the called procedure indicates success by returning ER_OK, ParseReturnValue is not used.
