Code:
#!/bin/ksh

echo > aux

while read label
do
   valor=1
   echo $label | grep "AS-"
   if [ $? -eq 0 ]
   then
      while read labelold
      do
         if [ "${label}" = "${labelold}" ]
         then
            #echo "encon" >aux2
            valor=0
            echo $valor
            break
         fi
         echo $valor #<--- Allways is 1
      done < hosts.old
      if [$valor -eq 1]
      then
         echo "$label" >> aux
      fi
   fi
done < hosts

After assigning the value 0 to your variable, you break the while loop so you never display the variable with the new value 0.

Whith KSH the modification of variable inside loops aren't lost (that is not the case with bourne shell).
Try the following script:
[CODE]var=init
ls | while read file
do
var="Last file is $file"
done

intval - Get the integer value of a variable

SYNOPSIS
int intval (mixed $var, [int $base = 10]) DESCRIPTION
Returns the integer value of $var, using the specified $base for the conversion (the default is base 10). intval(3) should not be used on objects, as doing so will emit an E_NOTICE level error and return 1. PARAMETERS
o $var - The scalar value being converted to an integer o $base - The base for the conversion Note If $base is 0, the base used is determined by the format of $var: o if string includes a "0x" (or "0X") prefix, the base is taken as 16 (hex); otherwise, o if string starts with "0", the base is taken as 8 (octal); otherwise, o the base is taken as 10 (decimal). RETURN VALUES
The integer value of $var on success, or 0 on failure. Empty arrays return 0, non-empty arrays return 1. The maximum value depends on the system. 32 bit systems have a maximum signed integer range of -2147483648 to 2147483647. So for example on such a system, intval('1000000000000') will return 2147483647. The maximum signed integer value for 64 bit systems is 9223372036854775807. Strings will most likely return 0 although this depends on the leftmost characters of the string. The common rules of integer casting apply. EXAMPLES
Example #1 intval(3) examples The following examples are based on a 32 bit system. <?php echo intval(42); // 42 echo intval(4.2); // 4 echo intval('42'); // 42 echo intval('+42'); // 42 echo intval('-42'); // -42 echo intval(042); // 34 echo intval('042'); // 42 echo intval(1e10); // 1410065408 echo intval('1e10'); // 1 echo intval(0x1A); // 26 echo intval(42000000); // 42000000 echo intval(420000000000000000000); // 0 echo intval('420000000000000000000'); // 2147483647 echo intval(42, 8); // 42 echo intval('42', 8); // 34 echo intval(array()); // 0 echo intval(array('foo', 'bar')); // 1 ?> NOTES
Note The $base parameter has no effect unless the $var parameter is a string. CHANGELOG
