-. Declaration of global variables
-. Definition of data tables for logging of data
+=====CR6 Basic Editor=====
-. Definition of user functions
+There are two methods for implementing the desired behaviour on the CR6. One method is to use a program called Short Cut, the other option is to use the CR Basic Editor. Short Cut can be used for simple tasks such as sampling a sensor at a set interval and storing the data, CR Basic Editor is the only suitable alternative for the USV system. The CR Basic programming language is based on BASIC, which is a programming language that was released in 1964 (26). Although CR Basic has functionality that was seen in the original BASIC language, it is a lot more similar to newer procedure- oriented dialects of BASIC. The operating system (OS) on the CR6 automatically runs the program when the device is turned on. Only one program can run, and a program can only have one thread. Hence, the OS does not have the characteristics associated with a real-time operating system (RTOS). That does restrict the number of options for implementation of the system functions, but it could be positive for future developers who are not accustomed to the particularities of RTOS.
