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 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
