Hello

Wasn't that what you wanted?

(*Definition*)

Clear[x, F00, f00];
f00[] := Block[{x, y, expr},
   expr = x^2 + y;
   Print[" expression now is ",
    ToString[expr, FormatType -> TraditionalForm]]];
F00[] := Module[{}, f00[]];

(*Call*)

F00[]

(*gives*)

 expression now is x^2+y

Best Regards
Norbert Marxer
