"init:"  determinds, that the following code, will be "initiation" code.
As such it will be called at the very beginning of the programm:



The above code will create a command block, which then will execute the command "/scoreboard objectives add my_object dummy"

"execute:#" determinds the beginning of a new commandLine.
A commandLine can contain up to  3840 command blocks.
All commands in a commandLine (excpect determind otherwise) are chain_command_blocks.
Note: All commandLines get called parallel.

"repeat"
followed by "(Nx)", for N ∈ ℕ \ {0} and x = any character or character
sequenz, determinds, that the following code will be repeated N  times (startign at 0), x
is a count variable, which allows access to the actuel loop.
repeat has to be in init: or execute:#:


The above code will create 2 command blocks with the command "/scoreboard players add @a my_object 0" and
"/scoreboard players add @a my_object 1"

"var"
determinds the declaration of a variable, once declared a variable can
be accessed anywhere by putting the name in "%". A variable also need
to be initialized directly:


The above code creates two command blocks with the commands "/time set day" and "/summon Zombie ~ ~1 ~ {NoAI:1}"

In CBS you can also create arrays:


Every row represents 1 value of the array.
To access a array just write the name in "%" and put in the value you want to acces (starting at 0).
"#say %my_array[1]%"

In CBS you can also declare functions, the following code shows a simple function:


In the above example, we declare a new function called "foo" without parameters and call it later.
When we call a function, the function gets replaced by the actual code, in this example only one command
"/say i am a function!".
You can also call a function inside a function, but be aware recrusive functions aren't possible!


A function with parameters:


The above code will create a command block with the command "/summon Zombie ~ ~1 ~ {NoAi:1}"

And you can of course pass function parameters as parameter to other functions:


The
example above first initiates the scoreboard and creates a variable
called "object", the commandLine contains 2 command blocks with the
commands "/scoreboard players add @a my_object 1" and "/say added 1 to
all for my_object"

Parameters are used in order to change the proccess of generation.
CBS knows 9 different parameters:
