Skip in a $GENERATE

[Mike S. Whitlow]

Yeah, I've just started to experiment with $GENERATE myself.. 

I have a Perl script that generates records for me already.. Unless I can find a quick way to
exclude records, quicker than doing multiple ranges which would be fairly quick, $GENERATE isn't
gonna save me any time and I will continue to use my Perl script..

: I have never used $GENERATE.  If I had to create records like

:      $GENERATE 1-254 $ PTR host-192-168-29-$.funwithdollargenerate.com.

: I would write a quick-and-dirty awk script to generate the lines.
: Then I could delete any of the output lines that I did not want.
: (Others might use something other than awk.)
