How do you compute '*'? That is, how do you know how many more iterations you have to go before you're done?
Should you really be handling this sort of thing through an "iteration count" mechanism? How do you keep track of which iteration you're on? Is it another detail that needs to be handled behind the scenes, or is the index of the current iteration available to the programmer? (Remember, we're dealing with 'while' and 'loop' as well as 'for'.) -- Jonathan "Dataweaver" Lang
