This compiler error will occur if you try to assign a value to any of the system variables.

For example:

n_TokenDate = EncodeDate(1999,1,3) // not allowed

Note that the compiler will assume that a variable is a system variable, and generate this message, if the variable's second character is an underscore. This, even if no such system variable exists (eg. n_Elvis, n_BartSimpson).
