Hi, I have an array holding a mixture of numbers and single letter strings (e.g., {1, 2, 4, 5, A, B, C} ). I am using the following sub-function to search for a given letter (e.g., ‘Q’) but it only works when I search for the numbers. When I search for any string, I get the index corresponding to the letter ‘A’ only. Why is this? 
sub find
{
 my($var, @array);

  $var  =$_[0];
  @array=@_[1..$#_];;

  my $index = 0;
  ++$index until $array[$index] == $var or $index > $#array;

  #print "@array\n";
  #print "$array[$index]\n";
  return $index;
}


$result = &find (‘Q', @fsg);
print "$result\n $fsg[$result]\n”;  # returns index for the first non-
+integer regardless of what that item is

$result = &find (‘2', @fsg);
print "$result\n $fsg[$result]\n”; # returns correct index

$result = &find (‘102', @fsg);
print "$result\n $fsg[$result]\n”; # returns the length as the array a
+s the index - which is the value I check to see if a match occurred o
+r not.
