Hello,
      Which version of Perl are you using? I ran this code and it seemed to
work
as I expected it to (both as a single file, and as a pair of files).

I'm using the MacPerl appl version 513r2.

My understanding of the semi-colon as terminator is that it is optional in
blocks with single statements (though recommended since you may later add lines
to the block). I'm ready to be corrected (ooh yes please!!), though!

Bob
