My 2 cents:

Quote:
FILES="data/*"
Are you sure you have no sub-directories?...


There are file test operators, so use them e.g: -b, -d. -f, -s
Code:
if [ -s $X ]
   then
       awk '{x[NR]=$0; s+=$0; n++}
       ..
   else
      echo  "NA, NA" ....
  fi

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 SEE ALSO
