Hi,

	That is a very hard problem in Pascal to solve. You have 2 solutions :
   1 you take a such function from a book or from a website
   2 you write it

        If you decide to write it, you should be a good programmer in
Pascal. (you have to know pointers...) So, if you want to have your
function now, it is better to download it. But it can be a good exercise
to write it. If you want, i can explain you better how to write such
function. For instance, i wrote, 2 years ago, a such function which
recognizes more thatn + \ * and -, and which can derivate the function
given by the string..
