RPN calculator

[srvaldez]

here's a simple RPNcalculator, made with WinFBE.
it's not quite perfect, there's no keyboard input and that's beyond my ability to implement.
RPN Tutorial https://hansklav.home.xs4all.nl/rpn/

the stack size is 1000 but only the first 4 are displayed.
corrected some bugs and added the ability store values in variables A thru G
to store a value that's on the stack into A, press Quote then A then STO
to put the value stored in A onto the stack press A

added:
a single click on a value on the stack will copy that value to the clipboard
the Copy button or a double-click on the stack will copy all values to the clipboard
the Paste button pastes values in the clipboard to the stack

added:
updated the calculator to handle keyboard number and arithmetic operator entry, also the enter or return key act as the return button.

the bas file is garbled?

Seems to have a utf8 bom attatched.
You'll need an ide like poseidon to open the .bas file.
Anyway I get
File not found, "WinFormsX\WinFormsX.bi"
It is not in my afx folder.
Must be in the WinFBE editor??

The .exe runs OK of course, after a discussion with Win 10 anti-virus.

In the meantime

Code: Select all

#include "crt.bi"
system_("calc")
sleep  

as a poor substitute.

thank for testing, yes you need to compile with WinFBE or perhaps copy the contents of the WinFBE_Suite\FreeBASIC-1.06.0-win32[64]\inc folder to your FB distribution, have not tested this, so I suggest you make a backup of your inc folder, just in case.
the bas file has a UTF-16 BOM and it's likely that the files in the inc folder are also UTF-16 and so would only work with a Unicode able IDE
this project was an exercise to get familiar with the WinFBE Visual designer and perhaps inspire others to give it try.

I WinFormsX includes are part of the WinFBE Suite download or can be downloaded separately from https://github.com/PaulSquires/WinFormsX
Those includes are regular ANSI files.

In a WinFBE project you can have ANSI, UTF-8, or UTF-16 encoded files *however* any visual designer created source code file in WinFBE will always be UTF-16.

this completes the calculator project, the calculator is actually usable :-)
