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.

I have uploaded a new version with minor improvements and bug fixes.

Duplicating a sprite in console window.
Code:

    REM  SPRITE1.BAS
    REM  HOBBY BASIC INTERPRETER

    BLUE = 1

    DIM ROBOT[15,10]

    PATH$ = PATH('DATA\ROBOT.HB')

    LOAD PATH$, ROBOT[]
    IF V0 = -1 THEN ALERT 10H,'NOT FOUND',PATH$ : END

    VIEW 11
    SCREEN 80,25,300
    CURSOR 0,0
    COLOR 0,0
    CLS


LOOP#

    X = RND() % 65
    Y = RND() % 15

    GRAB X,Y,15,10,ROBOT[],2

    REPAINT X,Y,15,10,BLUE,(RND()%15)+1

    WAIT 20

    IF ~KEY(27) THEN GOTO LOOP

    CLS : END

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 have uploaded a new version with minor improvements and bug fixes.

A set of functions is now available for sending UDP messages across the network to a remote host Server-Client examples are included.

P2P Drawing via UDP sockets in the console.

The changes appearing in real time between the 2 computers.

I have uploaded a new version with minor improvements and (not so minor) bug fixes.

Introducing Text Draw, a simple ASCII design program for the Windows console written in Hobby BASIC.

(If someone could run the program in a Windows 10 environment and confirm that the mouse is working, I would appreciate it. I had some minor issues with Windows 10, I made some corrections and changes, but i haven't tested them, since I don't have often access to Windows 10).

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!

Thanks for taking the time running the examples bitRAKE, i appreciate that.

I think i have to update my code a bit. The interpreter using the same mouse routine since 2015.

Out of range!, i missed that, it's better this way.
Code:

    if p > SIZE(charset[])-1 then break

Oh come on now, how fast did you notice that. A true game tester Wink

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.

I see it with the test programs I write. Some, while running smoothly on previous windows versions, behave differently in windows 10, even in the legacy console mode.

I can do it through HB as well. Something like...

Code:

    alert  (0x4|0x20),"","Do you want to compile all the examples?"
    if V0 = 6
        exec "if not exist BIN\NUL md BIN"
        exec "FOR %G IN (.\EXAMPLES\*.BAS) DO (HB ""%G"" -bind "".\BIN\%~nG.EXE"")"
    endif
    


Thanks again bitRAKE.

I have uploaded a new version with minor improvements and bug fixes.

The PRINT AT command can print characters while retaining the background color of empty cells.

A snake game for the console. It takes advantage of this new ability of the interpreter.

Hobby BASIC can execute a program located on a remote server directly from the command-line.
Code:

    HB.exe https://sites.google.com/site/hobbybasicfiles/TEST.BAS
