CGI & looping

[jeff]

for one thing you don't need to specify the iterator $_ in the foreach loop.
it's used by default. and i dont think you can use a foreach as a paramter to
the print statement.
try using join {map} to print the data list if it has to be a paramter, or
otherwise, print it separately.
