( in this example I use "TOS" to mean "Top of Stack" )

( Here is a one-line word, `f`, that computes the nth fibonacci number. )
: f 0 1 rot 1 ?DO swap over + LOOP swap . ; 

10 f . ( compute the 10th fibonacci number. )
       ( `.` pops the computed fibonacci number off the stack and prints it. )
       ( the stack is empty once again. )
