G'day 345qwerty,

"Do you have any suggestions?"

If you write code that messy, you can be pretty much guaranteed to make mistakes. Choose a code layout that suits you and use it consistently. See "perlstyle - Perl style guide" for tips on how to accomplish this. Consider using "perltidy - a perl script indenter and reformatter". 

open(FILE, "<", "Q.txt");

Use lexical filehandles instead of global, package variables. Check that I/O operations actually worked. See open and the autodie pragma. 

        while($number <= $#column) {       #go through the array from 
+0 to the last element
                   $number++;
                 }

This is an inappropriate method for iterating an array. If you just want the elements: 

for my $element (@array_name) {
    # Do something with $element here
}

[download]

If you really need the indexes: 

for my $index (0 .. $#array_name) {
    # Do something with $index here
}

I might have further suggestions after you've tidied up the code.

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


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
