the program you are proposing for discussion is a good example for bad

The program I showed was the only way you can write a while (true) loop in
Robolab with a break statement to terminate the infinite loop. It is Robolab’s
standard implementation of that good programming practice.
My point was that strings attached to the ‘end’ corner of a jump icon have no
logic connection anywhere other than to the begin corner of the land pair.

Nqc is brillant, ... Dave you did a great job out there. BrickOS is a great
result of the open source idea and the programmers should have our
estimation. LejOS simply is amazing. And I love PbForth ! Ralph, that’s so
cool. But forgive me: all this was yesterday.

I appreciate your sentiments, but there is absolutely no doubt in my mind that
you are wrong. Modern text-base languages will long outlive the fad of
graphical programming. Saying otherwise is like saying that people will quit
using Ctrl-X, Ctrl-C, and Ctrl-V in favor of reaching over to the mouse and
picking a menu item to do the equivalent. People who do that today are slow and
every day they are being overtaken by the people who learn to keep their hands
on the keyboard at all times if possible. Or its like saying that we’ll someday
stop typing words on a keyboard and pick words from a list of predefined
frequently used words on a palette (possibly digging around through several
palettes after enabling the highest allowed language level) and stringing them
together with the mouse. Nothing about graphical programming improves on what
can be done with (and arguably cannot help but provide less ability than and be
more difficult to learn than) text-based languages.
