Hi, Wim.

   If I remember correctly, Boland doesn't recommend mixing their TV
   OOPs stuff with their procedure stuff.  Probably for the very reasons
   you specified - the event driven stuff.  (I wonder what event driven
   stuff is doing under DOS. :)  )

   What the ref manual does specify is following a series of steps to
   carefully extract the procedure stuff and use it with a TV
   interface - which I am inclined to follow to avoid buggy software.

   That's curious.  Do I understand you correctly that you convert your
   (Borland) Pascal stuff to Windows and it was less difficult than to
   TV?  Did that include with Windows PM?  I think I may be doing that
   next using the procedure approach - without OOPS and TV.

WV>As for Pacal for OS/2. There is a patch available for Borland Pascal 7.0 to

   Yes, I heard about that 16-bit release last year for OS/2 by that
   German magazine.  Someone told me that Borland gave them permission
   to do what they did - so they wouldn't have to.  Still doesn't make
   too much sense to me that Borland would do this - but what the hey,
   some people obviously preferred a half a loaf to none.

   The 32-bit Pascal Beta, I heard it is called "spos2" release for OS/2
   is also coming from a Germany company - and not from Borland.

   I will wait to hear the reviews from those who have time to try it.
   I am glad there is something available.  I just hope there are only
   minor problems and it is a professional version and incompatibilities
   with Borland's Pascal is minimal.

   From what I hear of the number of people using Windows tho, I am
   still inclined to do Windows next and then OS/2.  This way both
   development systems will become stronger, and more reliable, in the
   market place.   That is what I think right *now*, but I will make
   that decision when I am on the verge of going beyond DOS.

   DOS, as far as I can tell, still has the largest market place due
   to it's simplicitiy for most users. It appears this will remain true
   for most non-professional users for some time to come - perhaps for
   many years to come.  I don't think I want to ignore DOS users.

   Plus, I hear that many users have 286's/386's, and few, in
   comparison, have moved on to the 486's - so that DOS market looks
   healthy and well and big enough to merit giving considerable
   attention to right now.  Next year will have to wait till next year.
   :)

   You know what they say about pioneers?  They wind up with arrows in
   their backs.  :)  I have had my fair share of arrows in my career.
   Now I don't have to be on the technological cutting edge all the
   time.

   Being on the edge as far as my apps is concerned is enough for me
   right now.  I have to be ahead of everyone there - or else.

   What do you think, Wim?

   BTW, do you have any products released yet?  For where - Europe or
   the USA or both?
