I'm using the following, thanks to the input of some on this list:

foreach $KEY ($query->param())
{
        $VARNAME = uc($KEY);
        @$VARNAME = $query->param($KEY);
        $$VARNAME = join(",",@$VARNAME);
}

This works fine except in one case I have come across. If $KEY begins with 
1 through 9, I get

Modification of a read-only value attempted at the $$VARNAME = join() line

If $KEY begins with a zero or any other character (I really didn't try ALL 
others), it works fine.

Anything I can do about this?

Steve
