Example of IN super for procedure and function

[GaneshP]

Hi,
cane any one give me example of IN SUPER for internal procedures and functions, how to use

 

[jdpjamesp]

What have you researched so far?

 

[GaneshP]

inproc internal procedure is there in main.p and sub.p programs, after added sub.p as a super-procedure in main.p.
in this case how to use IN SUPER Keyword ? please explain ?

/* main.p */
define var hdl as handle.
run sub.p persistent set hdl.
this-procedure:add-super-procedure(hdl).

run inproc.

procedure inproc:
message "Main.p inproc".
run super.
end.



/* sub.p */

procedure inproc:
message "Sub.p inproc".
end.

IN SUPER is used to declare that the function is found in a super procedure and that the function is implemented in the super procedure.

/* main.p  */
 define var hdl as handle.

FUNCTION TodaysDate RETURNS DATE () IN SUPER.

 run sub.p persistent set hdl.
 this-procedure:add-super-procedure(hdl).

MESSAGE "The date is" TodaysDate() VIEW-AS ALERT-BOX.

/* sub.p */
procedure inproc:
   message "Sub.p inproc" VIEW-AS ALERT-BOX.
end.

FUNCTION TodaysDate RETURNS DATE ().
    RETURN TODAY.
END FUNCTION.

It is not used for internal procedures and for these look at this example:

/* p-podrvr.p */
FUNCTION SetPartName RETURNS INTEGER (INPUT a AS CHARACTER) FORWARD.
     
DEFINE VARIABLE h AS HANDLE.
DEFINE VARIABLE localPartName AS CHARACTER.

/* Add a super procedure */
RUN p-posupr.p PERSISTENT SET h.
THIS-PROCEDURE:ADD-SUPER-PROCEDURE (h).
SetPartName("2000 Calendar").

PROCEDURE sample1:
    DEFINE INPUT-OUTPUT PARAMETER a AS CHARACTER.
    a = a + "proc: Part name is: ".

   /* Invoke procedure sample1 in the super procedure. */
    RUN SUPER (INPUT-OUTPUT a).
END PROCEDURE.

FUNCTION sample2 RETURNS CHARACTER (INPUT-OUTPUT a AS CHARACTER).
    a = a + "func: Part name is: ".

   /* Invoke function sample2 in the super procedure. */
    SUPER (INPUT-OUTPUT a).
    RETURN a.
END FUNCTION.

FUNCTION GetPartName RETURNS CHARACTER ():
    RETURN localPartName.
END FUNCTION.

FUNCTION SetPartName RETURNS INTEGER (INPUT partname AS CHARACTER):
   localPartName = partname.
END FUNCTION.

/* p-posupr.p */
/* Defines a new version of the internal procedure sample1 and a new version of the user-defined function sample2 
DEFINE VARIABLE h AS HANDLE.

FUNCTION GetPartName RETURNS CHARACTER () IN H.

PROCEDURE sample1:
    DEFINE INPUT-OUTPUT PARAMETER a AS CHARACTER.
   
   h = TARGET-PROCEDURE.
    a = a + GetPartName().
    MESSAGE "TARGET-PROCEDURE is:" TARGET-PROCEDURE:FILE-NAME VIEW-AS ALERT-BOX.
   MESSAGE "SOURCE-PROCEDURE is:" SOURCE-PROCEDURE:FILE-NAME
   VIEW-AS ALERT-BOX.
END PROCEDURE.

FUNCTION SAMPLE2 RETURNS CHARACTER (INPUT-OUTPUT a AS CHARACTER):
   h = TARGET-PROCEDURE.
   a = a + GetPartName().
   RETURN a.
END.
