Any "print" command will use the expression evaluation routine.
I find it harder to understand the evaluation routine without having
a look at expression.h (for the expression "tree"), and the associated
parsing routine. See c-exp.y, that shows how the expression tree is
built, will show you what data is where in each node depending on the
node kind.
