Folks, Just a quick question, in below script if user input is "Enter key" then I can't return to main menu. It defaults to condition 3 (I don't understand why)?
Can you please suggest me how can I detect an Enter key. I was trying to use Switch fuction but its not working in PERL V 5.8.4. Appreciate your help. 
#!/usr/bin/perl


local ($bak_id)=shift;
local ($acc_bal)=shift;

$bak_id=<STDIN>;
$acc_bal=<STDIN>;
chomp ($bak_id);

print "bak_id = $bak_id\n";
print "acc_bal = $acc_bal\n";


if (($acc_bal < 1.0 ) && ($bak_id eq "BOTH")) {
            print "condition 1\n";
                }

elsif (($acc_bal > 1.0 )&&($bak_id eq "BOTH")){
        print "condition 2\n";
            }

elsif (($acc_bal < 1.0 ) && ($bak_id eq ("Cust1")||("Cust2"))) {
        print "condition 3\n";
            }

elsif (($acc_bal > 1.0 ) && ($bak_id eq ("Cust1"||"Cust2"))) {
        print "condition 4\n";
        local ($choice);
        $choice=<STDIN>;
        if ($choice="YES") {
            print "condition 4.1\n"    
                         }
        elsif ($choice!="YES") {
            print "condition 4.2\n";
        
                        }
                }
elsif (($bak_id eq "\n") || ($acc_bal eq "\n")) {
        print "return to MM\n";
        }

else {
    print ("Returning to Main Menu\n");

    }
