Enabling weak internal pull up resistors on port B

[DDDvvv]

datasheet says that they are controlled by OPTION_REG , bit 7 (RPBU). (pg. 45)

same page indicates that on reset, this register value defaults to all bits being set, (1111 1111),

so, hook up your switches, dont change nothin' and switch away

Ok, So let's say for some reason the OPTION_REG is getting reset. What syntax do I use in PicBasic Pro to set it again?

option_reg.7=0

I've often found internal pull-ups troublesome and simply use small external resistors between 4.7K and 10K depending on the input device

In that thought process, it appears option_reg.7 = 0 sets all 4 port B pull ups on an 16F88. Can one of those pins then be used as a serial output? I don't see where you can set individual pins.......

On a 16f690, I do this to get the weak pullups working...

option_reg.7=0 ' Enable WPUs by individual pin 
WPUB = %11110000  'enable weak pullups on RB7, RB6, RB5 & RB4

It all works weally weakpullup-tastically (but disable any other PIC stuff that maybe sharing those ports...and make sure they're all set as inputs)
