Like most of my recent projects, this one was programmed in ROBOLAB.  I have already said a few good words about this program and I will only talk about how truly compact it is.  This program is not trying to do something really fancy, but all of it is contained in half a screen.  That makes it very easy to work with and debug.

I would also say how much I appreciate the work of Eric Wang et al., for their text book on the use of ROBOLAB, now in version 2.5.4C.   It is:

But ...why build a Watch Winder?
