* `$door(pos, text)` - Open/Close a door at position "pos".
Example: `$door("123,7,-1200", "close")`.
Hint: Use the Techage Info Tool to determine the door position.

Get the description (item name) for a specified itemstring, e. g. determined via the TA4 8x2000 Chest command `itemstring`:
`str = $read_data("223", "itemstring", 1)`
`descr = $item_description(str)`
