With the function TYPE() the type of a variable can be determined. The function
operates on the pointer to the variable, and returns a value corresponding to
the variable type as follows:

    Float          0
    String         1
    Long           2
    Boolean        3
    Float array    4
    String array   5
    Long array     6
    Boolean array  7
    Word           8
    Byte           9
    Word array     12
    Byte array     13

Note: An invalid pointer returns the value -1.

Example:

    a$="test"
    x%=4
    DIM y(3)
    PRINT TYPE(*a$),TYPE(*x%),TYPE(*y())

--> The numbers 1, 2, and 4 appear on the screen. (*a$, etc, represent the
    pointer to a variable.)
