Roland:
I don't want to be too critical because I know how hard such an endeavor
can be. In fact,
I applaud your efforts. But, I find your idea of testing naive. You've
got some good ideas,
but a couple of days of testing is not really sufficient for a project
like this. For example,
let's look at %nlobs. What happens if the data set does not exist? You
get an ERROR:
message. That might be a design decision, but I don't think it is a
very good one. What
would be better is if you returned a value that could be recognized
(personally, I would
use 0, but YMMV). Also, the user may be interested in counting
observations with
respect to a WHERE clause. You could add that functionality to %nlobs
or I suppose
you could create %nlobsf. But, you have to be careful since the nlobsf
parameter wasn't
in 6.12 with the rest of the functionality; it was added at 7.0. So, in
summary, more
testing, and especially more user testing, is warranted. If you want to
subscribe to
buzz-words, you could even consider "validation", but I don't go that
far myself.
