Fantastic, this also solves another conundrum. Amibroker really is quite something. 

Many thanks

  Hello,

  Variables are passed by VALUE, not by reference hence changes made inside the formula
  do not affect them.

  If you want to return one value use a function.

  If you want your procedure to update many variables, pass the NAMES of the variables instead
  and use VarSet() function inside procedure to set the values of the variables defined externally.
  Note that you should make sure that your procedure does not define local variables of the same name
  because local variables will then "cover" visibility of global ones.

    Subject: [amibroker] Procedure Help Please


    I have a procedure with 4 input arrays e.g.

    Procedure ABCD(A,B,C,D);
    {
    ABCD updated here ...
    }

    Within the procedure, I update A, B, C, & D. 
    How do I ensure I get the updated values when I reference them in the code after the procedure is called. 


    Many Thanks

    DJ
