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.)
