well, it has more to do with how than version.  I had put all of Rick's examples
into a file and run them - I knew I was having a little bit of a problem of
assignment and left over values, (which is why the vx1... series was
introduced).

Using the command line interface rather than rolling all the examples into one
file (and allowing for re-use of already assigned values <veg>)...
I get the same results you do for 6, and 7 was already the same.

As to versions...
Linux (a) 5.005_03
Linux (b) 5.6.0
NT 5.6.0

And 7 was the same between yours and mine. The differences were a matter of
representation - vx1 was probably undefined - I didn't bother putting -w onto
the perl line and put "" to describe the lack of value into the description
because.. hmmm.. well - I just did.
