Specifying the parameters to a procedure with a ``++PLIST++`` makes that procedure unusable from free-format code. Instead, prototypes should be used - both when defining a procedure and when calling it. They have the additional benefit of allowing you to use keywords such as ``++Const++`` to better-specify how parameters are passed to a procedure. Further, the use of a prototype instead of a ``++PLIST++`` is cleaner and more consistent with the code required for subprocedures.
