Hello: I'm having trouble getting the following to modify the MATCHED line in my flatfile, why isn't it rewriting / replacing the old line with the new line?
sub modify_flat_file{
    open (USERFILE, "$flat_file");
    $ID_matched = 0;
    while (<USERFILE>) {
        chop($_);
@f = ($a, $ID, $b, $c)=split(/\|/,$_);
        if ($f[1] eq $FORM{'ID'}) {
        $ID_matched = 1;
        last;}
            close (USERFILE);
        if ($ID_matched == 1){
print USERFILE "$FORM{'new_a'}|$ID|$FORM{'new_b'}$FORM{'new_c'}'\n";
