I have a perl script xyz.pl:-

#!perl -w
use strict;
my $param = shift;
eval print $param;

sub egal () 
{
        my $result;
        my @arg = @_;


        $test = $arg[0];
        @test = grep (/$test/i, @arg);

        print "++++";

        if ($#test == $#arg)
        {
                $result = true;
        }
        else
        {
                $result = false;
        }
        return $result;
}

Now I am calling the script :-

perl xyz.pl 'egal("20090316","7006")'
[download]

I want the script to eval the parameter and return me the result. The output should be like:

"++++false"
[download]

But it is not returning me any result. On the other hand if I set a variable to the value whatever I am passing through parameter and then pass the variable to eval, it is giving the desired output

#!perl -w
use strict;
#my $param = shift;
my $param = egal("7006","7006");
eval print $param;

sub egal ()
{
         my $result;
         my @arg = @_;


         my $test = $arg[0];
         my @test = grep (/$test/i, @arg);

         print "++++";

         if ($#test == $#arg)
         {
                 $result = "true";
         }
         else
         {
                 $result = "false";
         }
         return $result;
}

Now I am calling the script :-

perl xyz.pl
[download]

Output :

++++true
[download]

So now how do I make the first piece of code work... so that I can make the sub program call dynamic??
