Hello, I'm just trying to figure out where I stand in my learning of perl could someone please point out any sloppy coding, ways I could better do different parts of my code, and anything you can tell me that will help me become more better with my perl coding. =) thanks. 
#!/usr/bin/perl -w
use strict;
my (@eachnum, $binary, $good, $decimal);

print("\n\nEnter a binary number:");
    chomp($binary=<STDIN>);
if ( $binary =~/\D.*/ ) { 
    print("Not a binary number!\n");exit;}
if ( $binary =~/\d.*/ ) { 
    @eachnum = split (//, $binary);
    $good = 1;
    foreach (@eachnum)
    {
    next if /0/ || /1/;
    print("A binary number contains 1's and 0's!\n");
    $good = 0;    
    last;    
    }
    if ( $good == 1 ) {
    convb2d();
    }
} 

sub convb2d {
    $decimal = unpack 
( "N", pack("B32", substr("0" x 32 . $binary, -32 )));
print ("Decimal: $decimal\n");
exit;
}
