oops I've maybe got the post right this time I'm a bit messed up with $_ The code below failed to work til I was specific as what to write. In the IF block "print NEW;" worked but in the ELSE block it failed, but once I explicitly used $fields[0] it was fine. $_ has me a bit frustrated with loops in loops as to which $_ I'm using. Regards Ian. 

    while (<UNMATCHED>)
        {
        @fields = split(/:/, $_);
        $wd = substr($fields[0], 0, 1);
        if($wd eq "/")
            {
                my $rtn = search ($fields[0], UNUSED);    #Returns 1 i
+f #fields[0] is found in UNUSED.
print "Return is = $rtn \n";
                if($rtn == 1)
                {
print "Writing to CHANGED. \n";
                    print CHANGED "$fields[0] \n";
#                    print NEW;                #This works in IF but n
+ot in ELSE ?
                }
                else
                {
print "Writing to NEW \n";
                    print NEW "$fields[0] \n"; #This works
#                    print NEW;                    #This does not
                }
            }

        }
