Quick Macro Help?

[Thortok2000]

I want a macro that does this:

Turns on (but not off) melee attack at my target.
Sends pet to attack
Casts highest rank of Corruption

I want a similar macro for Shadow Bolt.

Please respond soon. Thank you. ^_^

/startattack
/cast PetAttack
/cast Corruption (or Shadow Bolt)


or

/startattack
/pet attack
/cast Corruption


Edit: Oops, made a small mistake.
