An argument is defined as a value sent to a function, or to expressions or lookup tables.

Different functions require different amounts of arguments;

• time() requires no arguments. You need therefore not write the parenthesis, but can call the function using only the name: time.
• sin() requires one argument - the angle
• mod() requires two arguments - the value and the divider
• max() requires two, or more, arguments and will return the highest of the given arguments.
• A lookup table which has been configured to accept arguments accepts only one argument - the lookup key.
• An expression which has been configured to acccept arguments requires exactly the number of arguments as the configuration specifies.
