trouble with gawk and columns

I am trying to make a script that would take the highest value of each columns for example

Code:
cat file
0     0     0     0
0     8     9     1
3     8     3     9
7     7     7     7

the results would be
Code:
7     8     9     9

I found this code, and it takes the highest value with a single column. I am going for all the columns

Code:
BEGIN { max=0
	print "The most expensive car is"
      }

$5>max { max=$5
	 result=$0
       }
END{print result}

I tried putting in a for command to try and take the max of all the fields but I get a syntax error for the $count>max {max=$count line.

Code:
{       for (count = 1; count <= nfields; count++)   
                        {
                $count>max { max=$count
                        }
                print max
                }

Can I get some help with this script or some insight to make this work thank youuu.Smilie

NAME
Locale::Codes::LangFam - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangFam; $lext = code2langfam('apa'); # $lext gets 'Apache languages' $code = langfam2code('Apache languages'); # $code gets 'apa' @codes = all_langfam_codes(); @names = all_langfam_names(); DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in ISO 639-5. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5 language family codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langfam('apa','alpha'); $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages. This is the default code set. ROUTINES
