(A%B)	if A % B = 0, one line down
;	Begin of a comment, have to be at the start of a line
~INSTRUCTION	Run a command once (Then ignored in main-loop)

A program is running infinitely, until the "end" command. With this, you are able to easily run a while loop.

Every instruction got no spaces, so its possible to write those next to each other, separated with a space, for example:

>Hello,_World!
end

becomes

>Hello,_World! end

Examples

Hello, World!

>Hello,_World! end
