[racket] Help with simple macro

Thanks William.  Its not a for loop that I'm looking for, but rather a scope within which I have access to the sequence.  A typical case will be where I have two procedures within the scope that are recursive but also pass control to each other under certain conditions, and each of these procedures accesses the sequence.  


Cheers,
Harry
