I was wondering why this doesnt work. I have an array of numbers. I use a while loop as follows to split the array.

while(<>)
{
    @array = $_;
    @array = split;

}

The description of your problem doesn't match the code sample you give. You don't have an "array of numbers". You have an array to which you're assigning twice for every while loop, reading from a file. You're not "splitting the array". You're splitting line of text into an array. Only the data coming out of the last line of text will be there ater the loop. Oh, and the first assignment does nothing at all.

This splits the array via new line. Every element of the array holds a string of numbers. The element $array0 for example might contain the following data.

No, it may not! Incidentally, if you use square parens either use html entities or enclose in code tags as appropriate: [whatever] has a special meaning to PM.

As another poster suggested to you, you be looking after a bidimensional array. I suggest you first read some introductory tutorial to Perl, though.

• 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).
