I am aware that object-oriented programming does not talk about CONTROLS,
but I am trying to express the conceptual problems that the parents I 
described
might have when trying to take a jump from FORTRAN to LiveCode, possibly
via object-oriented programming.

Unfortunately, in Bulgaria, everybody thinks that C++ is the bee's 
knees; mainly because this is what they teach in the
Mathematical specialist High Schools (they "teach" Pascal in the other 
High Schools - which is a farce as the teachers don't know Pascal and 
the teenagers are sufficiently switched on to realise that it is old hat).

Now, I am not going to deny that C++ is a powerful programming language; 
but what I do know (even if, for the sake of argument, LiveCode
is less powerful and less capable than C++), is that LiveCode beats the 
kilt off C++ in terms of getting young kids programming and understanding
the underlying concepts of programming.

However, the parents I have to explain things to, who are computer 
programmers, learnt their stuff in the 1980s and work in places
where they have no need to learn more contemporary languages (note that 
I am avoiding the stink-word: 'modern'), and have never really
given a moment's thought to what might happen if they suddenly find 
themselves at the road's end with a severance envelope.

Just to really bang my message home: in Bulgaria's tax offices 
everything runs on DOS, using tax packages that were adopted when
DOS was the latest 'thang'.

Now, I don't actually see anything wrong (unlike a lot of other people) 
about using DOS and DOS-based software packages if they do the
job that is required (why spend money and buckets of time retraining 
staff when your system works 100% the way you need it to?).

What I do see as wrong is that very many adults, having done their 
training when they were at University (say in their early 20s) have never
felt any need to update their knowledge about anything whatsoever since 
they graduated. This applies to teachers, doctors, lawyers and
so on, as well as computer programmers. But, this is very much the 
majority view here in Bulgaria [this *may* be one of the reasons that
Bulgaria is very much at the bottom of the "treacle well" when compared 
with other post-Communist bloc countries].

I'm not that interested, as, at the moment, at least, LiveCode does 
almost all that I require (let's leave communicating
back-and-forth between USB devices out of this discussion).

What I am interested in is how to communicate adequately to people who 
have grown up with 3G languages the
very great advantages (particularly from a pedagogical point of view) of 
LiveCode.

While the C++ book I bought makes interesting reading, in parts, I 
cannot see myself bothering to learn to code
anything beyond the most pedestrian stuff in it: even if for the simple 
reason that all that bother about
"/edit, preprocess, compile, link, load/ and /execute/" gives me the 
willies.

In fact, thinking about "/edit, preprocess, compile, link, load/ and 
/execute/" I really wonder what RunRev think they are doing,
as the lack of all the fiddly stuff is half of what makes LiveCode so 
much better. RunRev's propaganda machine hasn't got off the ground!
