Creating Requesters

Using the OCCURS clause creates an array structure. In the previous example,
GROUP1 is an array structure that occurs three times. In some applications, you
need to know where the cursor is within the list when you invoke a service.
You can pass the current cursor position to a service by using either the
@CURSOR-FIELD pseudofield or the @CURSOR-POSITION pseudofield.
@CURSOR-FIELD sends the screen field name and subscript number of the
current field to the service. @CURSOR-POSITION sends the Working-Storage
group name, field name, and subscript number of the current field to the service.
In both cases, the subscript number corresponds to the index number of the array.
Refer to “Using Pathmaker Pseudofields” in Section 9 for more information about
@CURSOR-FIELD and @CURSOR-POSITION.
You cannot pass @CURSOR-POSITION from one requester to another requester.
