UML Sequence Diagrams


I am creating sequence diagrams to show the dynamic nature of my model.
I am having difficullty in representing a hierarchy of method calls in
a sequence diagram. For example take the follwoing example. I want to
call methodA(), but I walso want to show that this in turn calls,
methodB() which calls MethodC()

class General
{
methodA()
{
methodB();
}

methodB()
{
methodC();
}
methodC()
{
print ("Hello");
}

}

Can this be done in sequence diagram?

I am using Rational Rose I'm not sure if this is a limitiation of the
tool or UML. I'm sure Rational Rose does not implement UML 2.0

Thanks
