Writing an output byte instead of single pin

Hello People,

I'm new to arduino and have veeery basic atmel knowledge.

I'm looking for a way to write a bit pattern to the outputs, for example to write 00010001 to outputs 20-27. Is there a simple way?
Something like on atmel loading 00010001 into a register and then performing "out portB register#".

I've performed some searches on "output byte" but didnt find anything (or didnt understand the english ;))

thanks!
