_RC^TYPE
_RC^TYPE declares function procedures that can be called by a thread procedure (but
are not themselves thread procedures) and that return a frame return code value.
_RC^TYPE also declares variables to hold the frame return code (_RC^) values such as
values returned by _RC^TYPE function procedures.
The special return code _RC^NULL may be returned by an _RC^TYPE procedure to
indicate that it has not returned any valid frame return code. _RC^NULL must not be
returned to the frame by any thread procedure.
Example
In this example, a thread procedure calls an _RC^TYPE procedure. The called
procedure returns a frame return code, which is interpreted by the calling procedure.
_RC^TYPE PROC process^object ( ... );
BEGIN
.
.
END;
_THREAD^PROC (_COMMAND^PROC);
BEGIN
_RC^TYPE obj^rc;
.
.
obj^rc := process^object ( ... );
IF obj^rc <> _RC^NULL
THEN
RETURN obj^rc;
.
.
_END^THREAD^PROC;
_RC^WAIT
The thread returns _RC^WAIT to the frame to wait for the next event.
_RC^TYPE PROC procname ;
_RC^TYPE var1, [ var2 [,...]];
RETURN _RC^WAIT;
