What is the affirmative formal command form of the verb?

In the formal, there is no distinction made between negative and positive commands. In the informal, it DOES make a difference. Example: the verb venir. Formal command is venga. ¡Venga aqui ahora mismo! - Come here right now! ¡No venga aqui ahora mismo! - Don´t come here right now! In the Informal, positive, the Word is "ven". ¡Ven aqui ahora mismo! The negative would be "no vengas." ¡No vengas aqui ahora mismo! - Don´t come here right now!
