print "Input values, one per line. When you're done entering the value
+s press the Enter Key on a blank line.\n";
print "\n";

@x = ();
while($value = <>)
 {
 chomp($value);
  if ($value eq ""){last;}
 @x = (@x , $value);
 }

#  Input will be counted.

$count = 0;

foreach $line (@x)
 {
 $count++;
 $count = @x;
 $sum += $line;
 }
#  Error check to make sure user entered at least one value.

if ($count < 1)
 {
 print "ERROR: You must enter at least one value!\n";
 }
 else
 {
 print "You inputed $count value(s).\n";
 print "\n";
 }

&aver;
&min;

print "The minimuim value of the input is: $min\n";
print "\n";

print "The average of the value(s) you entered is: $av\n";
print "\n";

#  This subroutine will take the sum of the input values, divide by th
+e number of values, and return the average.

sub aver
 {
 $av = $sum / $count;
 return $av;
 }
#  This subroutine will find the minimum value of the user input.

sub min
 {
 my @num;
 @num = @_;
 my $min;
 $min = $num[0];
  foreach $i (@num)
   {
   if ($i < $min)
    {
