   I agree fully with what Duncan says in this discussion about TPU
incompatibility across the different versions of Turbo Pascal. 
Fortunately eg TP Numerical Methods Toolbox came with sources so I
have been able to update those of my programs that relied on it.  On
the other hand not wanting to release my own sources, I've had to
release four different versions of my PD units collection, as I'm
sure many readers of our newsgroup know.  No big deal really, since
I have batches to take automatically care of any update trough all
the versions.  But on the other hand I must own (or rather my
University, for me) each TP version. 
   We have been writing a bit negatively about TP, because of some
aggravating features and policies.  But in all it is still an
excellent product.  One recent sideline, which I have had the
opportunity to look at, is Turbo Profiler.  Really useful for
testing code efficiency for critical parts of a TP program.  Comes,
incidentally, with a similar user interface as TP 6.0.  Dialox boxes
etc.  (Motto: If nothing else helps, press TAB :-)
