I just started learning Perl; this is the first program i've ever tried to write. I can't really figure out what i'm doing wrong (one, because I don't know, and two, because my interpreter won't stay open long enough to tell me; it closes right when the program finishes). Can anyone help me figure out what i'm doing wrong? This is supposed to find primes between two numbers. (And if you could help with the interpreter issue, that'd be nice, too). 
<code>      
    use strict;
    use warnings;
    #finds prime numbers between two points;

print "Please enter the values for the 2 numbers between which you wis
+h to 

find the primes.\n";
$x=<STDIN>; chomp($x); print "\n";     #user inputs point x;    
$y=<STDIN>; chomp($y); print "\n";    #user inputs point y;
for($i==$x; $i==$y; $i++){
    $even=0;
    $notprime=0;
    $j=$i/2;
    if(int($j)==$j){
        $even=1;        # tests to see if it is even;
    }    
    else{
        $n=$i**(1/2);
        for($m=3; $m=$n; $m+=2){
            $o=$i/$m;
                if(int($o)==$o){
                    $notprime=1;
    }
        }    
            }    

    if($even==0 && $prime==0){
        print "$i is prime!\n";

        }
    }
        

$q=<STDIN>; # stops the program from closing...;

If anyone wants to help me figure out what's wrong... just let me know what you did? Thanks.
