while the absence of backward compatibility is something of a nuisance,
I can live with it as long as TP is moving onward towards making our
life as programmers easier.

I don't want TP to become a standard ! Look how hard it is to move
standards ! I like the fluidity of the various changes and I am expecting
more...

After dabbling for a while with Turbo Vision, I sens that this is but
the begining of the story. I expect the next version of TV to be somewhat
incompatible with the current one. And I am prepared to live with it as
long as the changes are worth it.


My feeling is that Turbo Vision is nothing more but a gentle introduction
to concurrent (or if you like Multi-tasking) processes. The idle handler
is rudimentary, yet this kind of environment begs for concurent processing and
I feel that that is where we are heading.

The way TP is growing makes me think of a sphere: growing uniformely in
various directions: modules, objects, assembler, event-handling ...
concurency seems to be one of the next steps. 

After all, TP *is* moving quickly, and we had better get used to these
annual changes.

Nobody said that driving a car was intuitive.
