</div><div>That's great to hear that Pascal has served you well with scientific programming and the like. I confess unfortunately I'm not familiar with the units, but I will be happy to see if I can help optimise them in places, either by writing platform-specific assembly language (with a Pascal fallback if it's not Intel x86_64), kind of my speciality, or compiler improvements.</div><div><br>

<br>
I am asking questions on the art of scientific computing from 1966.
<br>
After Algol and Modula,
<br>
the U.C.S.D. Pascal system has been the touchstone of the scientific
<br>
computing. This has
<br>
been devoted by Niklaus Wirth book and applied in Borland TP7 software.
<br>
The only thing
<br>
scientists need is a strongly typed language with pixel access on a
<br>
single graphical windows.
<br>
This is needed, for instance, by Monte-Carlo simulations. We need the
<br>
full power of the
<br>
computer with the pixel definition of the result because the eyes are
<br>
the best investigators
<br>
for scientific bugs. TP7 with graph was the best tool for that. For less
<br>
mathematical
<br>
approaches, like 3D models it was sufficient to use Borland Delphi-7.
<br>
Now, in 2019, it was
<br>
possible to use FPC compiler with Fp-IDE to make in laboratories good
<br>
simulations of
<br>
scientific equations, very clean in FPC Pascal, with the Graphical tools
<br>
PtcGraph, PtcCrt, etc
<br>
... It is far more useful than old Seymour Cray Fortran or C// on
<br>
Connection Machines CM1 / CM2
<br>
of Hillis : Theses need M.I.T. gourous in big National Laboratories.
<br>
Some years ago, it was possible with the good job of Nikolay Nikolov on
<br>
Ptc Pascal Units, to do
<br>
clean-proof use of computer to visualize physics in HDMI 1920 x 1080 x
<br>
65536c under Windows.
<br>
With lesser resolution, a work in Pascal was running without
<br>
adding/changing a word under
<br>
Windows_Intel / Ubuntu_Linux / or Raspbian_Raspberry Rpi3. Now, for
<br>
scientific use, it is not
<br>
possible because ptcgraph etc... are not included in latest versions,
<br>
for instance of Raspbian.
<br>
So, in order to use software in Physics, we are compelled use old
<br>
versions of OS 2.6.4 Fpc
<br>
systems instead of 3.0.0 on /usr/lib/fpc to use our programs. It is a
<br>
big problem for us because
<br>
we are interested by easy Pascal simulations of physics and we are
<br>
newbie in systems. Will it be
<br>
an hope to have again under Fpc : PtcGraph, PtcCrt, PtcMouse... to do
<br>
good job in physics ?
<br>
<br>
Friendly Yours.
<br>
<br>
P.S. I beg your pardon for my desesperately rusty English language
<br>
because Classrooms are very
<br>
<br>
far from me in time ... ( I am 73 ) .
