Provides a character string value returned
by the most recently executed RETURN statement of a local or remote
procedure, trigger block, user-defined function, method of a class,
class constructor, or property accessor.
Example
For
examples of the RETURN-VALUE function, see the RETURN statement reference
entry.
Notes
- The
returned value has the CHARACTER data type.
- When you access RETURN-VALUE, its value represents the value returned
by the most recently executed RETURN or THROW:
- If it is a
RETURN with options that can set the RETURN-VALUE, but does not,
the empty string ("") is returned.
- If it is a THROW that returns a Progress.Lang.AppError object, the
value of the object's ReturnValue property is returned.
- To reliably access a RETURN-VALUE setting returned from a block or
called routine, check RETURN-VALUE as soon as you can after the block
or called routine terminates.
- RETURN-VALUE does not return the value of a non-VOID method of
a class or user-defined function invocation. You return the values
of these methods and functions within an expression where you reference their
invocations, similar to referencing a variable value.
- For more information on returning results from remote procedures, see OpenEdge
Application Server: Developing AppServer Applications.
