Hello all mates, I am a new user to this site and a beginner with PERL. I am trying to get input form keyboard and the am comparing it with stored value but its not working, instead if i dont take value from keyboard and hard write it in the code then it works. 

Non-working code:

#! usr/bin/perl -w

$dynamic = 'D';
$nvolatile = "NV";
print ("Enter class: ");
$storage = <STDIN>;

if(($storage eq $dynamic) || ($storage eq $nvolatile))
    {
        print("\n $storage");
        print("\n Done");
    
    }
else
    {
        print("\n $storage");
        print("\n Wrong Class");
    }

Problem Elaboration: When i run above mentioned program and take D or NV as input the if condition fails. -------------------------------------------------------- 
Working Code:

#! usr/bin/perl -w

$dynamic = 'D';
$nvolatile = "NV";
print ("Enter class: ");
$storage = 'D';#<STDIN>;

if(($storage eq $dynamic) || ($storage eq $nvolatile))
    {
        print("\n $storage");
        print("\n Done");
    
    }
else
    {
        print("\n $storage");
        print("\n Wrong Class");
    }

------------------------------------------------------ Please help out to clarify my concept if there is any missing point.
