Just like any other high-level programming language YCP has typed variables to hold data of different kinds:

Data type void
Data type symbol
Data type boolean
Data type integer
Data type float
Data type string
Data type byteblock
Data type list
Data type map
Data type term
Data type path
Data type block
Data type symbol
Data type any

2.1. Data Type void (nil)

This is the most simple data type. It has only one possible value: nil. Declaring variables of this type doesn't make much sense but it is very useful to declare functions that need not return any useful value. nil is often also returned as an error flag if functions fail in doing their job somehow.
