Last month I made 2 examples for the Array object. I felt they were lacking in practical application so I have created a new example combining elements from both.
In this (fully commented open source) example, you walk around picking up and dropping items. Each item has a name, description and weight which is stored externally in a file called "Items.dat". Frame 2 of the example is the editor for this file. Hope this is helpful. Cheers!
