Some functions require more than one parameter. The way you can how many parameters is needed is by looking at the documentation. The first source of information is the Function Library within RobotC. This will generate when you compile a program. RobotC will also hide some of the more advanced functions from this list. To see them you need to change your menu level.

At the most general level, everything in a program can be separated into two general groups: Commands and Data. The main difference between these groups is the ability to store information. Commands can only perform actions while data is information that can be acted upon.

The main data types that we will work with are:
