I use the book, which I have had for a few years and find a very useful
reference and source of procedures I can use in my programs.

I am not an expert on Pascal as a language. I just use it for writing
programs, in its Delphi form. The current Delphi may well differ from
the original definition of the Pascal language in many ways but this
does not matter to me. I would guess that like most programmers I just
use a sub-set of the facilities available in the language. If it works
efficiently then I am happy,whatever it looks like to some relatively
arbitrary criteria.

As an engineer I am trying to do some large number-crunching calculaions
in the CFD field so the criteria for the language are whether it is
close to natural English and therefore easy to write and check and
modify and whether it runs quickly when compiled. Pascal/Delphi has the
advantage that it is strongly typed and has a well-defined syntax and a
very fast compiler. If you can get the code to obey the syntax then it
will probably do what you want it to do.
