Evaluation symbol...

[salvomic]

hi,
please, help to get evaluation symbol (|) in a program...
I would get this:

Code:


EXPORT lagrangeValue(lista_x, lista_y, xValue)
BEGIN
  LOCAL y, temp;
  y:= lagrange(lista_x, lista_y) | X=xValue;
  RETURN y;
END;

but the | symbol isn't evaluated...
What's the correct syntax?

thank you,
Salvo
