pro confusion

I am unclear on what pro and pro-1 means. It is not making much sense. Also is an imperative marked in a sentence with a simple asterisk because i have never seen this before.

PRO(also seen as PRO 2, see link below) represents you. For example, HOME PRO. In English, You are home. PRO 1 represents I or Me. For example, PRO-1 DETEST HOMEWORK. In English, I hate doing homework.

Also imperatives are marked with a asterisk, for example *SIT*. You must also accompany that with direct eye contact. Other examples of imperatives are *GO NOW* or *COME HERE*

Hope this is helped.

Giliane provided an excellent resource. I'd just like to add that the asterisk is new to me, too. If you choose to use it, that's fine by me.
