Hi filox, the source is not available, at least not yet. Hobby Basic has still some way to go. I want to extend the command list, find methods to make the intepreter faster, add features like user procedures with parameters and local variables and some other ideas i have. This is done somewhat slowly, the only days i can steal some time to work are the weekends.

Hi picnic, if u can share code with us, we can help you possibly to improve it faster and i'm interested in it for educational scope Very Happy

Hello, it is very interesting. I was very fond of qbasic. I'd just say that it would be nice to see your page in English, Greek is a bit hard for me Smile

I think I ran all of them on Windows 10.

About the mouse one: didn't indicate which button was double-clicked, and the middle button displays as the left button. This might be a limitation of the API - I don't know.

I did find an error in the XONIX game. I was able to meet the edge at the same time as the red spot. This causes the area not to be filled until I completed another closing move. This typically is just a "one-off" error.

Also, an error in DRAW.BAS, line 336, changed to "if p > 269 then break", and it seems to work.

Was only missing 1200 baud modem sounds. Very Happy

Well done!

Another oddity is not being able to select a character from the codepage that characters are displayed with. The saved images display correctly, but limited character selection as seen in the picture. I was even able to crash the console by selecting different fonts. Windows 10 might be to blame here as they try to push everyone to Powershell.

Putting this in a batch file will compile all the examples:

Code:

FOR %%G IN (.\EXAMPLES\*.BAS) DO (HB "%%G" -bind ".\BIN\%%~nG.EXE")

...assuming the batch file is with HB.EXE and a directory .\BIN\ has been created. Change the double "%%" to a single "%" to run the command directly at the prompt.
