stack = **RetStack**()
 
==== Parameters ====
 
None.
 

 
==== Returns ====
 
After the call, stack contains the call stack, as a field mark delimited variable.


==== Examples ====

Return Stack in Event Code:

<code>
/* the current procedure will be at the top of the list in List<1>.  The procedure that calls it is next, in List<2>

*/

 

declare function RetStack

List = RetStack()

CurrentProc = List<1>

CallingProc = List<2>
</code>
 

If this code is run from the window OIPI_PLAY, in application EXAMPLES, from the button BTN_RETSTACK, the return stack will be:

<code>
List<1> =  $$$EXAMPLES*CLICK*OIPI_PLAY*BTN_RETSTACK
List<2> =  RUN_EVENT
</code>


Return Stack in Stored Procedure:

<code>
/*  running the same code in a stored procedure called STARTPROC,
called from BUTTON_1 in the window OIPI_PLAY in the EXAMPLES application, the return stack is as follows:

List<1> = STARTPROC

List<2> = $$$EXAMPLES*CLICK*OIPI_PLAY*BUTTON_1

List<3> = RUN_EVENT
*/
