12C509 GPIO

Hi all,

I'm feeling a little stupid here but could someone tell me how to switch GP0,1,2,4,5 & 6 simultaneously?

I'm familiar with

bsf GPIO,4 ;set output GP4 high call delay ;call the delay subroutine bcf GPIO,4 ;set output GP4 low

But a list of bsf GPIO,1 bsf GPIO,2 etc. can't be correct surely

Could someone please enlighten me as to the correct way?

TIA
