in reply to Changing %s to (Info: %s)

The =~ operator and s/// don't work the way you use them. You should also be seeing some warnings from Perl about

Useless use of private variable in void context at ... line 10.

which should have made you suspicious about your code.

I think what you likely want is to learn about how =~ applies to variables, via perlop and perlre. I guess the following line could meet your intentions:

(my $linefinal = $line) =~ s/.../.../;

I see that you took some time to actually gather test input and output, but please test your posted code before posting it - your code doesn't read from the DATA handle.

    Thanks I inserted it and now it does make some changes only that it cuts out the %s just writing (Info: )...

    This is the message (with \%s OR %s in the s statement):
    Use of uninitialized value in printf at ./changer.pl line 11, <READER> + line 73.

      Could you try the code as posted? That error shows you are still reading from a different file handle than DATA. Try getting the examples posted here working and then once those work adapt them to your own needs.
