Help with AWK -- quick question

Ok. I'm just starting to use AWK and I have a question. Here's what I'm trying to do:

uname -n returns the following on my box:

ftsdt-svsi20.si.sandbox.com

I want to pipe this to an AWK statement and make it only print:

svsi20

I tried:

uname -n | awk '{ FS = "." ; print $1 }'

But that prints:

ftsdt-svsi20

How do I get it to exclude everything before the "-" and everything after the "."?

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
