Sure -- your version of "awk" is an old one that doesn't support that
feature.  Except for the first chapter or so of the AWK book, the examples
depend on having a more modern version of awk.  If you have a command "nawk"
try using that.  Otherwise, you can obtain the new flavor of awk from the
AT&T UNIX System ToolChest, or from UNIX System V Release 3.2 or later,
or a (supposedly) functionally equivalent utility called "gawk" from the
GNU project.
