while($i>=0){
&printline($i-1,@store);
&revline($i-1,$count,@store); $count++;
pop(@store);
}
sub printline{
($itemp,@printarray)=@_;
for($j=0;$j<=$itemp;$j++){
print "$printarray[$j]";
}
}
sub revline{
($it,$cou,@linarray)=@_;
if ($cou==0){
for($k=$it;$k>=0;$k--){
print "$linarray[$k]";
}
print '/n';
return;
}
$p=$cou-1;
$r=2*$p + 1;
for ($j=1;$j<=$r;$j++){
print " ";
}
for($k=@linarray-1;$k>=0;$k--){
print "$store[$k]";
if ($k==0){
print '\n' ;

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.
