Probably depends which version of awk you are using. The version distributed with HP-UX supports up to 200
($0 .. $199). You might be able to do some subtraction using $NF if you cant access a field directly.

An alternative would be to use the 'cut' command or, even better, perl.

cut

CUT(1)								   User Commands							    CUT(1)

NAME

       cut - remove sections from each line of files

SYNOPSIS

       cut OPTION... [FILE]...

DESCRIPTION

       Print selected parts of lines from each FILE to standard output.

       Mandatory arguments to long options are mandatory for short options too.

       -b, --bytes=LIST
	      select only these bytes

       -c, --characters=LIST
	      select only these characters

       -d, --delimiter=DELIM
	      use DELIM instead of TAB for field delimiter

       -f, --fields=LIST
	      select only these fields;  also print any line that contains no delimiter character, unless the -s option is specified

       -n     (ignored)

       --complement
	      complement the set of selected bytes, characters or fields

       -s, --only-delimited
	      do not print lines not containing delimiters

       --output-delimiter=STRING
	      use STRING as the output delimiter the default is to use the input delimiter

       --help display this help and exit

       --version
	      output version information and exit

       Use  one,  and only one of -b, -c or -f.  Each LIST is made up of one range, or many ranges separated by commas.  Selected input is written
       in the same order that it is read, and is written exactly once.	Each range is one of:

       N      N'th byte, character or field, counted from 1

       N-     from N'th byte, character or field, to end of line

       N-M    from N'th to M'th (included) byte, character or field

       -M     from first to M'th (included) byte, character or field

       With no FILE, or when FILE is -, read standard input.
