The 'key', is that the standard pin I/O functions, cannot accept variables. They are replaced 'inline', with direct I/O to the specified pin. Hence with these, you cannot pass a value to a function, specifying a pin.
However you can generate your own version of the I/O punction, that will accept a variable.
Have a look at the thread "Accessing digital I/O from within a for loop", which has references to a number of different solutions.
