two things about your code:

1.	it looks like you're trying to make a permanent change to the
	parameter - if so, it needs to be passed by reference (i.e. it
	needs to be a VAR parameter).

2.	you've declared a function, but haven't returned a value (by
	assigning a value to the function's name.

Really you have two options here:

1.	Write a procedure that changes the value of its parameter

2.	Write a function that returns the changed string
