Optional display control parameter
There is an optional third parameter that controls which pieces of text are displayed in the article. Its value is treated as a binary number and will display the corresponding "bits". So setting the 4's bit will display SMS, setting the 2's bit will display the ship name, and setting the 1's bit will display the ID. If binary math isn't your thing, refer to these examples: These are the same optional parameters in use in the other ship shortcut templates. Some of the options above are silly in the case of World War I era U-boats, but are included for compatibility with other shortcut templates.

N.B.: Be careful with the third parameter if not using the second parameter. In the U-103 example above, the "|3=2" means set the third parameter to a value of two, while the alternate syntax shows using a pair of pipes, "||2", to position the value two in the third parameter position.
