Thanks again for this fresh view of another way of defining a short function - this is
very concise and this is the solution that
approaches the most my original way of doing things (on a syntax basis) even you defined
2 functions that must be evaluated each
time they are used instead of getting 2 values directly.
I only hope the execution time is not a way too long when compared to other approaches.
This will surely be very useful to me in a near future ...

Tom, you were absolutely right - your answer is really a functional one.
Sorry for my confusion about the way I interpreted your original suggestion. I was faulty
and your version was really OK. I simply
thought you were bad by writing ' tab_nbr (that is a lit-word) instead of my own string
"tab_nbr/" and so I have been fooled when I
substituted your original work for a modified one before really testing it. This is only
after testing MY OWN modification that
nothing more was operating.
However I didn't realize that I was the author of the glitch I reported publicly as yours.
Sorry about that.
You did well to tell me back that you were right because this learned me 2 other things
:
a) Don't take for granted that my own view is the only way to go - even if I really demonstrate
that everything is well-founded on
my part (and fairly that was not the case here) ;
b) Don't criticize too quickly other's work even if I think I am right - especially in
a public exchange - something that in the
present case I unfortunaltely did and I sincerely regret it but it's a little late now.
Sorry again for my blunder and I publicly ask you to excuse me for this uncalled-for
attitude, even if it was lead in part by some
misconception from me. I'll remember the lesson and please continue to reply to my questions
as you did before. I learned a lots
since my last to questions - frankly more than I thought I would ...
(I was once a victim of such a non voluntary discredit from an inexperienced student
and this really put me in a severe situation in
front of an entire class - I really don't know how I didn't catch this lesson better
than I did. Hope this will not cause you any
other prejudice to you since it is entirely my fault).
Regards,
Gerard
