Variables of a procedure type T may assume as their value a procedure P. The formal parameter lists of P and T must match. P must not be a generic standard procedure, nor must it be type-bound procedure, nor must it be nested in another procedure. A variable of a procedure type may also assume as its value the constant NIL. A procedure type declaration may be preceded by a Java modifier directive for this compiler.
