You also still working on the GPC-TurboVision ???

Yes, in some sense. I am still working on BO5. At the moment, it is the Windows platform which prevents me from going on. :-( Everything else in the low-level drivers more or less works, so I would like to start to implement the actual user interface objects.

However BO5 is not intended to become a drop-in replacement for Turbo Vision (just like GPC is not intended to imitate the Borland Pascal compiler) but something more powerful.

In case somebody wants to have a compatible replacement for Turbo Vision, there are (at least) two ways to get it:

* There is FreeVision which comes with FPK Pascal. It should not be too difficult to port it to GPC.

* Borland has released the C source of Turbo Vision (*not* the Pascal source) into the public domain. One could translate it to Pascal, imitating the functionality of the Pascal Turbo Vision.

I do not recommend to patch the "real" Turbo Vision to run with GNU Pascal because it would remain under Borland's license, so we could not freely distribute it. The only thing we could do would be to distribute the patch, so every owner of a Borland Turbo Vision license could apply it.

I'm only will using the objects for this part if I dont lose lots of speed (I think 5% it's worth).

I think the loss of speed will be less than 1% due to GPC's very efficient optimization algorithms. But one should try.

BTW: GPC is'nt perfect and this will take a long time too but I like it in spite of that.

So do I. What I really like is to have the possibility to get the source of the compiler; so if nobody else is fixing some annoying bug for me, I can try myself on it. I remember several letters I have sent to Borland without getting any answer besides "your letter has arrived" ...
