Stack items

Stack items are form elements used to define a stack-based layout in a STACK container.

To define a stacked layout within a STACK container, leaf stack items (typically, form fields, labels, buttons) are specified inside grouping stack items such as GROUP or TABLE.

The next example shows a stack-based form definition with a GROUP stack item containing two EDIT stack items:

LAYOUT
 STACK
   GROUP g1
       EDIT customer.cust_num, NOENTRY;
       EDIT customer.cust_name, REQUIRED;
   END
 END
END
