Hi! I have more arrays, they are the results of an html form, and each array may be empty or may have more elements.Every array that has elements I want to put it in another array using join, smth. like this: 
@a,@b,@c,@d,@e,@f,@g
if(@a){my $test=join(',',@a)}
else{ @a is empty I don't put it in $test}
if (@a and @b and @c){my $test=join(',',@a).'and'.join(',',@b).'and'.j
+oin(',',@c)}

So when my array is not empty I want to put it in $test using join if is empty I don't need it. I relly don't know how to make this selection. Thank you very much for your time.
