Assuming the header lines are only for clarity:

Code:
awk '{ 
  for (i=1; i<NF; i++) 
    printf "%s", abs($i - $(i+1)) \
      (i == NF - 1 ? RS : "\t")
    }
  func abs(x) { return x < 0 ? -x : x }
  ' infile

Otherwise:

Code:
awk 'NR == 1 { 
  for (i=1; i<NF; i++) 
    printf "Col_%dnew%s", i, i == NF - 1 ? RS : "\t"
	next 
	}
{ 
  for (i=1; i<NF; i++) 
    printf "%s", abs($i - $(i+1)) (i == NF - 1 ? RS : "\t")
	}
  func abs(x) { return x < 0 ? -x : x }
  ' infile

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
