:-) Busted! I used Pascal 1984-1993, and C 1986-present with C++ (hate
it) 1990-1998. So I long ago forgot the details of pascal, and program
pretty much every language with a C accent.

Busted again. I was thinking that nextt := num not only defined the
return value, but actually executed the return. Because that's how the
return statement works in C. I now know (remember actually) that the
assignment doesn't trigger the return.
