3.2 Example 1

The simplest possible procedure, which does nothing, occurs twice(!) in the source code as “nullsys” (2864) and “nulldev” (6577), sic.


  6577 nulldev ()
       {
       }

While there are no parameters, the parentheses, “(” and “)”, are still required. The brackets “{” and “}” delimit the procedure body, which is empty.
