If you use SETW to set the window you will find that the area for the status block and the loose item block immediately following are defined by wst ds.b <the number of bytes> The status area is $40 bytes long so that the loose item status block starts at wst + $40. Since the combined block is defined by ds,b there is no guarantee that all the values are zero. For that reason in my examples I clear the whole area thus setting all loose items to available. This clearing is done before the working definition is set up. To set a loose item to unavailable you just have to set the appropriate byte to $10.
