Hi JohnGG,

I tried running the script but this error kept popping up! Note that I modified it to take files:

my $FILENAME1 = "random.txt"; open(INFILE1, $FILENAME1); my @tests = map [ split ], <INFILE1>; my $FILENAME2 = "my_column_file.txt"; open(INFILE2, $FILENAME2); my @results; while ( <INFILE2> ) { my @cols = split; foreach my $idx ( 0 .. $#tests ) { foreach my $subidx ( 0 .. $#{ $tests[ $idx ] } ) { my @posns = split m{}, $tests[ $idx ]-[ $subidx ]; $results[ $idx ]-[ $subidx ] ++ if scalar @posns == grep { q{r} eq $cols[ $_ ] } @posn +s; } } } say qq{@$_} for @results;

the error was:

Can't modify anonymous list ([]) in postincrement (++) at gg.pl line 2 +0, near "] ++" syntax error at gg.pl line 26, near "say qq{@$_}" Execution of Jgg.pl aborted due to compilation errors.

Line 26 is this one: $results $idx - $subidx ++. Also I notice an error/flag in the last line. Should i change the say to print?

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
