Hi there again :)
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;
}
This splits the array via new line. Every element of the array holds a string of numbers. The element $array[0] for example might contain the following data.
12 44 111 445
The numbers are separated by tabs.
I now want to get at individual numbers from the element $array[0]. So, I attempted the following.
@line1 = $array[0];
print "@line1\n"; # this works
@line1 = split(/\t/);
$var1 = $line1[0];
print "$var1\n"; # this doesnt work
$var1 doesnt print. Could anyone please tell me why and what I could try to rectify this? Thanks

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).
