in thread how to append 2 lines

And your Perl code to join the lines is...

Hint: use three-argument form of substr to check the 72nd symbol of the line and use it again to replace the text. For example:

my $one = ("_"x9)."*__\n"; my $two = ("-"x15)."\n"; print "$one$two"; substr($one,9)="" if substr($one,9,1) eq "*"; print "$one$two";

Sorry if my advice was wrong.
