thanks for the help, i will have to digest this for a while! I dont think $s can be empty, as the hash is automatic i think, there are no invalid records in flatfile, i will check... i may have things confused. if so i apologise! danke

Thanks very much, you were all quite right, the first iteration found no value ( uninitialised! doh! ) so i made it increment from 0 before i did stuff on it.. now it works fine... thanks perl monks! `$alphabet{$s}++; open (DATA, ">> ./ATOZ/$s.shtml" )or die "can't open file: $s!"; if (($alphabet{$s}) % 2){ print DATA qq\|<tr bgcolor="#eeeeee">; } else { print DATA qq\|<tr bgcolor="#FFFFFF">\|; } close DATA;` [download]	[reply] [d/l]

    open (DATA, ">> ./ATOZ/$s.shtml" )or die "can't open file: $s!";
        if (($alphabet{$s}) % 2){
            print DATA qq|<tr bgcolor="#eeeeee">;
        } else {
