This is a very good idea but I think in general it is better to open gnuplot in persistent mode and write to its graphics terminal directly, using the Open Pipe mechanism. Gnuplot terminal, at least on windows, is very impressive (antialiasing, GDI+,...) and very fast. If an old and buggy fbgfx form...

Thank you all for the rapid and extremely helpful responses.

What's wrong with floating point in FB? Could you be more specific?

Which means that either your FB implementation of shellsort is very inefficient, or the C runtime sort is not a shellsort. Indeed. Here is an efficient implementation of ShellSort procedure SortShell(var A: TVector); var ua, N: LongInt; j, k, h: LongInt; ta: double; begin ua := High(A); N := ua; h ...

@marcov
I am in the process of migrating from fbc to fpc. I hope that Free Pascal is as fast as Free Basic.
Is it also a kind of gcc emitter?

Yes, it works for me. Thank you,

Hi All, I asked this question before but I did not get any answer, so let me ask again here. To be more specific consider the following program ' uses WinGUI(12) by Lothar Schirm #Include "WinGUI.bi" Dim As HWND Window_Main, Label_txt Dim As MSG msg Window_Main = Window_New (100, 100, 300,...

Hi All,
Is it possible to close a main window, return to the console and keep program running?
Thanks in advance,
