can be made a bit more readable: 

        $output_line = "$line\n";
        substr($output_line,  99, 1) = $juris1;
        substr($output_line, 148, 1) = $juris2;

or 

        $output_line = "$line\n";
        substr($output_line,  99, 1, $juris1);
        substr($output_line, 148, 1, $juris2);

Otherwise, it looks like the only problem you have is that you're not printing out the lines starting with "2", and you end the loop prematurly using last. 

    while (<INFILE>) {
        my $line = $_;
        if ( $line !~ m/^2/ ) {
            substr($line,  99, 1, "9");
            substr($line, 148, 1, "Z");
        }
        print OUTPUT $line;
    }

Are you having any other problems?
