G:\>gawk --version
GNU Awk 3.1.0

Going through the awk FAQ and converting the *nix examples to GnuWin32 
ones. At http://www.gnu.org/software/gawk/manual/gawk-
3.1.1/html_node/Single-Character-Fields.html there is a code sample with 
output of:

$ echo a b | gawk 'BEGIN { FS = "" }
>                  {
>                      for (i = 1; i <= NF; i = i + 1)
>                          print "Field", i, "is", $i
>                  }'
-| Field 1 is a
-| Field 2 is
-| Field 3 is b

But my attempt to a Win32 port is:

C:\>echo a b | gawk "BEGIN { FS = \"\" } { for (i = 1; i <= NF; i = i + 
1) print \"Field\", i, \"is\", $i }"

with a result that has an extra line(Field 4).

     Field 1 is a
     Field 2 is
     Field 3 is b
     Field 4 is       <<== extra output that is different in GnuWin32

What am I doing wrong in this case?

TIA,

Will

try

C:\>echo a b| gawk "BEGIN { ...
             ^-- note no space

MS-DOS echo command prints everything up to the end of the command, 
including trailing spaces

Manuel,

Thanks for that tip. It has cleared up a lot of confusion on some of the 
other problems that I was having in getting the correct results back from 
GnuWin32 gawk.

Just a quetion shouldn't the field separator be space.

You are passing args a and b to awk and then removing setting the field separator to "".
