"... atleast that is what I want..!"
and I want a pony... but I've never found a hayburner in my Christmas stocking.
Others monks have explained the shortcomings of your eval print $param; but, for emphasis:
>perl 848064_xyz.pl 'egal("20090316","7006")'
'egal(20090316,7006)' is $param at line 10
'egal(20090316,7006)'
Line 11 $param: |'egal(20090316,7006)'|
At 13, $test: 'egal(20090316,7006)'
Use of uninitialized value in concatenation (.) or string at 848064_xy
+z.pl line 22.

And, just BTW, note that your double_quotes -- the "s -- don't pass through the windows shell (my Linux box is down, but IIRC, you'll have a mirror-image issue there).
Here's your code, slightly modified at 5, 6, 9, 10, 12, 19 and 34 for illustration (thus, "line 26" in my previous reply is now line 38).
#!/usr/bin/perl
use strict;
use warnings;
# OP says: Now I am calling the script :
# 001: perl xyz.pl 'egal("20090316","7006")'
my $param = shift;
chomp $param;
print "\n\n\t $param is \$param at line 10\n\n";
eval print $param;
print "\n\tLine 11 \$param: |$param| \n";
sub egal {
my $result;
my @arg = @_;
my $test = $arg[0];
print "\n At 13, \$test: $test\n\n";
my @test = grep (/$test/i, @arg);
print "\t $test[0] \n";
print "++++";
if ($#test == $#arg)
{
$result = 'true';
}
else
{
$result = 'false';
}
return $result;
print " $result\n";
}
egal($param); # call the sub!

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).
