==========================================================

prohibitive form : dictionary form + na

To command someone not to do something in Japanese is very easy. Simply add な after the plain form of a verb.

For example, いく (iku) becomes いくな (ikuna - don't go), いう (iu) becomes いうな (iu na - don't talk), たべる (taberu) becomes たべるな (taberu na - don't eat), する (suru) becomes するな (suru na - don't do), くる (kuru) becomes くるな (kuru na - don't come).

So to answer your question on the negative imperative-form for "Don't do that!", it would be するな (suruna). The imperative-form for "Do that!" would be しろ (shiro).

One common situation where this form of speech is used is when the speaker has authority or a supervisor role over the listener.

ここに座るな！

きかいをさわるな！

心配するな！

If you go to Japan, you'll notice that imperative-form is also being used in some of the Japanese signs. For example, you may see the sign 入るな (hairu na), which is a "Do Not Enter!" sign, prohibiting you from entering an restricted area.
