Replace elements of array with elements from another array based on a third array

[deanhystad]

That is a brute force ugly way to do it. Look at my post again and think about this problem in terms of x and y. x will be things like "first", "second", "third" and y will be things like "0" or "1". How do you change "first" to an array index? How do you change "0" to a number.

This assumes you have to use the clubby "No change" or "Change third element to 1" strings to enter changes. This isn't too difficult to parse, but it would be better if no parsing was required.
