The error message should make it pretty clear -- you aren't inside a
function so you can't return() a value which is, by definition, what
functions (and only functions) do.** Not sure there's a great
reference for this though beyond the error message....
Incidentally, what are you trying to do here? The code doesn't really
make much sense to me -- do you just want samples = 5*(1:10) ?
** I think there's a subtlety glossed over herein: functional
programming purists can wince silently if they so choose.
