If my memory serves me correctly, Val is actually a function.

MyValue := Val(MyString);

var
  thestring : string;
  thenumber : integer or real;
  theerrorcode : integer;

  begin
     Val(thestring, thenumber, theerrocode);
      if code <> 0 then
          writeln('Error in string at ', theerrorcode)
      else
           writeln('The number you converted is ', thenumber);
  end

I'm kinda confused. Everytime I try to create a program with Val i get the code error message. Converting a string to an integer would be like converting six or '6' to 6 right? What about if I typed in my name, how would that be converted to an integer? Could someone please just explain the whole val procedure to me, and why I keep getting that error message when I run my program?
Thank you
Brian
