Hey Jussi,
I'd like to try figuring out why the Pascal program runs so much slower,
relative to Gambas, on my system than on yours. May I ask what version
of FPC you are using?

Well, as Fabien says, shows the Pascal code. I find strange that a
Something wrong here! Gambas and Pascal are different category programming
languages, interpreted and compiled. And thus this is hard to believe. So I
had to test this myself.

I guess I should have included my system information; just didn't think
about it being relevant at the time. Obviously, though, it is.

Just to be clear, I did not run 'polynom.gambas' as a script with the
she-bang specifying to use 'gbs3' to execute it. That *is* slow.
I executed it using gbs3 with the '-f' option invoking the JustInTime
compiler.
I also just now used the IDE to create a command-line application based

Ah ok, sounds more logical. Anyway, if you want to compare Gambas with a
compiled language, you should use the JIT compiler. And you must not use
it if you compare it with an interpreted-only language.
Absolutely, that would make the comparing fair. I'll test later with JIT.

My cleaning script didn't include rm -f /usr/local/bin/gbs3 and
apparently because of changed paths make install didn't overwrite old
version. So my gbs3 had version number 3.2.90, and no -f option (it was
simply ignored)!
Just to warn others, you may want to check whether you too have two
