Can you turn on/off multiple pins in a single line? "I think" I have seen other codes within the forum do this but cant seem to remember if or how it can be written out.

let dirsB = x make them outputs e.g. %11111111
let pinsB = x to switch them on/off e.g. %10101010

Commands which can turn on/high or off/low,
but not both on and off in the same command
Are the HIGH and LOW commands.
Eg
HIGH B.0, B.5, B.6, C.3

The TOGGLE command can change the state high to low and low to high of several pins
Some may already be high and others low - the state off all pins listed will be swapped/toggled:
TOGGLE B.1, B.3, C.5

Thanks, I got it. I have a rather large Halloween prop that I am working on the code. My first code using resume/suspend and I found it working well.

HIGH B.0, B.5, B.6, C.3

TOGGLE B.1, B.3, C.5

Nice. I learned something new today. It probably takes up the same memory as discrete high commands, but makes for a tidier code read. Thanks westaust55!

... can change the state... of several pins

I did not know either. The documentation is only reporting its action for a single bit. Thanks westaust55.

PS : related to documentation, but on an other topic.
In http://www.picaxe.com/What-is-PICAXE/PICAXE-Chip-Sizes/, instead of only I2C, could it be added the master/slave capability of each chip?

Actually, both the PDF and on-line manuals do say one or more pins:
HIGH pin {,pin,pin...}

... one or more pins:

I missed that!

A suggestion for the doc : "TOGGLE pin_1,pin_2,pin_3,... / Pin_x - is a variable/constant which specifies the i/o pin to use."

And a code example illustrating this case...

Because a number of people have thought the M2's offer I2C slave capability when they do not I have added that to the list on the page.

Pretty much what it states in the online version:
http://www.picaxe.com/BASIC-Commands/Digital-InputOutput/toggle/
In the Syntax line

TOGGLE pin, pin, pin...
