calling function inside procedure call

[Stribor40 <ikamzic@gmail.com>]

my skeleton code looks something like this.....

procedure Something

   --some declarations
   --
   --

   function myFunction (a: in String) return Boolean;

   function myFunction (a: in String) return Boolean is
   
       begin
 
          Put(a,3);   
          return true;
       end;


begin
...

..
  myFunction("Hello World");
...

..

end Something;

i am getting error "cant use function myFunction in a procedure call.

How would I make a call to myFunction?
