As shown above, all the code is the same except for the fact that they've all become Ds. Another command has also been added, which just signifies the start of the program. The Brain:D syntax is as follows:

(Starting token)(Code tokens)

With that being said, a hello world program, one of the most tedious programs you'll ever make in this language, is shown below.

:D D D D D D D D DDDDDDD DDD D D D D DDDDDDD DDD D D DDD D D D DDD D D D DDD D DDDD DDDD DDDD DDDD DD DDDDDDDD DDD D DDD D DDD DD DDD DDD D DDDDDDD DDDD DDDDDDDD DDDD DD DDDDDDDD DDD DDD DDDDD DDD DD DD DD DDDDD D D D D D D D DDDDD DDDDD D D D DDDDD DDD DDD DDDDD DDDD DD DDDDD DDDD DDDDD D D D DDDDD DD DD DD DD DD DD DDDDD DD DD DD DD DD DD DD DD DDDDD DDD DDD D DDDDD DDD D D DDDDD

Spaces are ignored, but they're included for clarity. If spaces weren't allowed, the program would look like:

:DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD

This hello world example was made in Python since coding it in actual Brain:D would take too long. Basically, Brain:D is meant to mess you up. The thing about this language is that in theory, you could type in a colon and as many Ds as you want, and there would be output.
