void
This keyword conforms to ANSI C. Thus, it can be used in three different ways.
1. Parameter List - used to identify an empty parameter list (a.k.a., argument list). An empty parameter list
can also be identified by having nothing in it. The following two statements are functionally identical:
int functionName(void);
int functionName();
2. Pointer to Void - used to declare a pointer that points to something that has no type.
void *ptr_to_anything;
3. Return Type - used to state that no value is returned.
void functionName(param1, param2);
volatile
Reserved for future use.
waitfor
Used in a costatement or cofunction, this keyword identifies a point of suspension pending the outcome of
a condition, completion of an event, or some other delay.
for(;;){
costate {
waitfor ( input(1) == HIGH );
