Description

Contains the value stored in the object. The value is often not an object property but rather an item property. This is why the first parameter is an item identifier. Many controls in Windows applications have only one item (item id = 0). These controls automatically use item zero if no item id is passed, Passing no item id passes the constant current_item which equals to -99 and it is the class responsibility to transform current_item to the correct item number (0 or whatever valid value).

An object need not be visible to set or get its value.

Use Changed_Value to set the value of a data entry object (DEO) if you want the new value to be saved (set the Changed_State of the DEO).
