Hobby Basic is my toy language interpreter written in assembly language. It has a BASIC-like syntax with a set of specialized console commands and functions. It handles ANSI encoding graphics with ease. It supports UTF-8 characters, keyboard and mouse. It has a small set of UDP functions. It creates stand-alone executable. Runs on Windows XP up to 10. It's implemented in fasm. Hobby Basic project started in 2015 and continues to grow to this day. Slowly, since it is a toy interpreter which I make just for my personal fun. My goal is to make an easy to use language, ideal for making text games with ANSI graphics in the Windows terminal console. Guess what, I think it's going well! Download Youtube Video A Hobby Basic program. Code:
rem TV.BAS
rem Hobby Basic Interpreter
a$ = 'N O S I G N A L'
dim bg[8] = 15,14,11,10,13,12,9,0
title a$
screen 80,25
cursor 0,0
color 0,0
cls
for x = 0 to 7
color bg[x],0
paint x*10,0,10,25,-1,-1
next x
erase 17
erase 18
erase 19
pen 15
at 25,18,a$
inkey
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 drag and drop TEST.BAS onto HB.EXE 
How to create the standalone DRAW.EXE Type at the command-line: Code:
hb EXAMPLES/DRAW.BAS -bind DRAW.EXE
A standalone application will be assembled. 
Notes for Windows 10 users. In later versions of Windows you will need to temporary disable real-time protection for Microsoft Defender. Antivirus programs do not like small executable files and often consider them (incorrectly) suspicious. Although Hobby Basic runs smoothly on Windows 10, however, one more option is to enable the legacy option.  Last edited by Picnic on 19 Jul 2021, 10:06; edited 258 times in total |

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.

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 0.0.1 Hobby Basic interpreter supports (partially) wide characters in the console via utf-8 encoding. 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.'
Almost everything may be replaced with wide characters in Hobby Basic. Code:
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  |

rem RND.BAS
rem Hobby Basic Interpreter
screen 80,25,300
color 0,0
cls
do
x = RND() % 24 + 2
y = RND() % 14 + 1
c = RND() % 95 + 32
pen c
at x,y,CHR(c)
until KEY(-1)
cls : end

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

I think i found what was causing the trouble. Give it a try if you like typedef.

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