This is not a seperate file, but a date area within the object file.

But this would only be apropriate for debugging -- which is a single usage
example. A much more practical example is a sprintf-like function:
  SPrints.Print("Var r holds value %r");

Or even creating SQL-Statments, where the following function handles quoting,
too:
  SQL.Fill("INSERT INTO Names (Name, Surname) VALUES ($name, $surname)" );
