Hobby BASIC is my toy language interpreter written in fasm.
It has a BASIC-like syntax with a set of specialized commands and functions.
It supports keyboard/mouse, and UCS-2 character set.
It handles ANSI encoding graphics with ease.
It has a small set of UDP network functions.
It creates standalone pseudo-executables.
It runs smoothly on Windows XP/7 and 10.
See notes for Windows 11 users.

Some Games coded with Hobby BASIC.

Hobby BASIC project started in 2015 and continues to evolve until now.
Slowly, since it is a toy interpreter which I make just for personal fun.
My goal is to make a simple to use language, suitable for game design in the Windows console.
Guess what, I think it's going well.

Download

A Hobby BASIC program.

Code:


    rem  TV.BAS
    rem  Hobby BASIC Interpreter

    a$ = 'N  O   S  I  G  N  A  L'

    dim a[8] = 15,14,11,10,13,12,9,0

    view 11
    title 'Channel 4'
    screen 80,25,300
    cursor 0,0
    color 0,0
    cls

    for x = 0 to 7
        color a[x],0
        paint x*10,0,10,25,-1,-1
    next

    erase 17
    erase 18
    erase 19

    pen 15
    print at 45,18,a$

    do

        copy 0,18,1,1
        move 1,18,79,1,0,18
        paste 79,18

        wait 150

    until KEY(27)

    cls
    end

How to run the examples.

Open the command-line CMD.EXE in the HB folder.
To run the TV.BAS example, type:

Code:

hb EXAMPLES/TV.BAS

Alternatively, simply click HB.EXE and select an example.
In Windows 11 you might need to unblock it first.

How to create the standalone TV.EXE

Type at the command-line:

Code:


    hb EXAMPLES/TV.BAS -bind TV.EXE

A standalone application will be assembled.

Notes for Windows 10 users.

Although Hobby BASIC runs smoothly on Windows 10, however, if you are having difficulties try enabling the legacy option.
Right-click on the application title bar and choose the Properties menu option.
Restart the console.

You might need to temporarily disable real-time protection for Microsoft Defender.
Antivirus programs do not like small executable files and often consider them (incorrectly) suspicious.

Notes for Windows 11 users.

In Windows 11 you have to get back legacy command prompt.
Change to have Windows Console Host instead of Windows Terminal as the default terminal app.
Apply changes and restart the console.
Enable the legacy option.

With a few simple tweaks, Hobby BASIC runs flawlessly on Windows 11.

Great stuff!
Things like that motivate beginners to start programming.

I suppose that the author's sentiment to QuickBasic was the main inspiration for this project. Nice thing. Smile

Nice. This prompts me to make a CLI graphics library. Looks pretty neat.

I am glad you like it guys, I had some concern whether it can be served as an example or a tutorial, due to the lack of the source code.

Hobby BASIC interpreter partially supports wide characters in the console via UCS-2 character set.

Almost everything may be replaced with wide characters in Hobby BASIC.

For Greek monotone characters, the prerequisite is the choice of the Lucida Console font.

Code:


    print 'Τη γλώσσα μου έδωσαν ελληνική'
    print 'το σπίτι φτωχικό στις αμμουδιές του Ομήρου.'
    print 'Μονάχη έγνοια η γλώσσα μου στις αμμουδιές του Ομήρου.'

    τύπωσε fix print
    ανάποδα fix reverse

    dim Διάταξη$[3] = 'Παλιά','Περιοδικά','Πληροφορικής'

    for ΜΕΤΡΗΤΗΣ = 0 to 2
        τύπωσε ανάποδα(Διάταξη$[ΜΕΤΡΗΤΗΣ])
    next

This is very nice.
Reminiscent of DOS apps.

Mouse handling would be a nice addition, I think Wink

If it can be understood then no worries.

Besides not all examples are aimed at beginners.

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

Mouse support in Windows console is now available.

This example demonstrates random colored characters in the console.

Code:


    rem  RND.BAS
    rem  Hobby BASIC Interpreter

    view 11
    screen 80,30,300
    color 0,0
    cls

    do

        x = RND() % 24 + 2
        y = RND() % 14 + 2
        c = RND() % 95 + 32

        pen c
        at x,y,CHR(c)

    until KEY(27)

    cls
    end

Thanks for the feedback typedef. Can you please tell me your Windows version and if you tried the rest of the samples?

Nice to hear!
Sure, it seems that an improper call to SetConsoleOutputCP function crush the program. By the way, i installed Windows 7.

A Tetris game for the console.

This is the first Hobby BASIC game ever made, and is still working today.
