Procedure to Set Booleans

Post subject:  Procedure to Set Booleans
What I would like is one procedure that will set all booleans but one I specify in the argument to false. Like this is what I want below:
Turing:

procedure SetAllFalse (onlyTrue : boolean)
   personalIconFade := false
   userIconFade := false
   documentsIconFade : false
end SetAllFalse

SetAllFalse (userIconFade := true)

I would like the above to turn all the booleans false within the procedure except for userIconFade.
Here is the actual part of my code and I have no procedure yet to do it, that's where I need the help.

Turing:

    if (startClicked) then
        if mousex > 220 and mousex < 320 and mousey > 395 and mousey < 415 then %main picture
            if ~personalIconFade and ~documentsIconFade then
                Fade (personalIcon, fadePicDelay)
            end if
            personalIconFade := true
            userIconFade := false
            documentsIconFade := false

        elsif mousex > 220 and mousex < 320 and mousey > 365 and mousey < 382 then %documents picture
            if ~personalIconFade and ~userIconFade and ~documentsIconFade then
                Fade (documentsIcon, fadePicDelay)
            end if
            personalIconFade := false
            userIconFade := false
            documentsIconFade := true

        else
            if ~userIconFade and ~documentsIconFade then %default user picture
                Fade (userIcon, fadePicDelay)
            end if
            userIconFade := true
            personalIconFade := false
            documentsIconFade := false
        end if
    end if

Right now, the only thing I can think of is to have an array of booleans and keep track of them by integer reference. Less readability, but the best of the two ways I can think of doing this.

The other (worse) way of doing it would be to pass a variable argument to the procedure. Set all of your booleans to false, then set the variable argument to true. By far, this is a bad way to do it, and is not recommended.

Why not do something simpler?
Turing:

SetAllFalse()
userIconFade := true

Oh ya to above post, good idea =D
I tried it when I first started my program and it was buggy but now it works.
