first off, you'll need something like this:

Turing:

proc swap (var a, b : string)

end swap


Now what you've done is created parameters that will change the variable you used. for instance:
Turing:

proc add_5 (var x : int)
     x += 5
end add_5

var num : int

add_5 (num)


Now if you put num, it will be five. If you define your parameter as a variable, it makes it mutible, so it will change it on the outside. Without var, it turns them into constants within that procedure.

So now that you know this, you have a simple task. Find a way to assign a and b's values to eachother
