Excuse the newb questions but I want to emulate XOR as in this example:

                        If Dat2 = 0 Then 
                            PassMidiGuitar = False 
                        Else 
                            PassMidiGuitar = PassMidiGuitar XOR True
                        End If

Where 'PassMidiGuitar' is of course the global.
Couldnt see mention of XOR in the vanilla PD?

Cheers

@image_engine Yeah I don't think there is a native object that does this, but you can always do this:

Thanks...but how do you impose a bit set? ie I want to set the 3rd bit of global variable "GV"? The example was a bit elemental...should have stated bitwise operator.

@image_engine It's probably easiest to use the [expr] object to build the expression that you want......
Look in pd/doc/5.reference/all_about_expr_functions.pd which is in your Pd installation folder.
[expr a ^ b] is probably the starting point, and you will recognise the operators......
but if you really need to get to binary for your ops then that is another problem........

Cheers...yeah I have used globals with binary flags so bitwise is what I need. They just seemed to logical way to go for mapping flags to a consistent, although linear object. I can probably get around it but hacks always = time....dont have a lot atm
