You have to change the field separator before you read the record or you have to force awk to re-evaluate the record to make the change in FS take effect. So, either of the following should work:
Code:
gawk 'BEGIN{FS="-"}  {print $2 " " $3 " " $1}' test

or
gawk '{FS="-";$1=$1} {print $2 " " $3 " " $1}' < test
Note that there is no need to use cat and a pipeline instead of the simple command letting awk open the file itself or using redirection in the shell to set the input file before kicking off awk.

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
