Programmable RPN Calculator

[NickyTi]

This is Programmable Calculator based on FORTH language ideas.
It's tested with fpc 3.2.2 and Lazarus 3.0, 3.2, 3.6, 4.0 for both 32- and 64-bit on Windows 8.1, 10, 11.
I would be glad if someone has the time and desire to compile and test it on other platforms.

My goals were to create a compact program using only the standard Lazarus components and learn how to use:

• UTF8 strings;
• stacks and queues;
• recursive algorithms;
• simple hash;
• messages for data exchange between units;
• context menus;
• events log;
• hints;
• themes and fonts;
• secrets of TSynEdit;
• TPageControl in Windows so that tabs have CLOSE and ADD buttons;
• i18n for multilingual localization;
• associations of *.forth files with the program.

To get a quick start from the context menu open 0.forth from the sample_files folder.
For Windows users: If you want to win in the StarTrek game, open star_trek.forth from the super_star_trek_en or super_star_trek_ru folders.

I am grateful to the ideas, tips and tricks of this forum and the Lazarus team for helping me achieve these goals.

Thanks

Hello NickyTi,

I had a very quick look at your program but, can say it looks quite interesting.

You may be interested in knowing that there is a typo in the opening page.  In the line that reads "Leo Brodie "Starting FORT." , it should be "FORTH" not "FORT."

By the way, compiled and ran your program on Win 7 SP1, 64 bit.  It seems your program is fully compatible with that version of Windows.
