Function Explanation
 RAND is used to generate a random number and the result is output to Out, within the range
0~32767.
 The input value does not have any effect on the random number to generate. But the value must be
input for In.
_8
 To get the random number within a specific range, users just need perform the MOD calculation
over the generated value and get the remainder. For example, the random number between 0
and10 can be generated by writing the program RAND(0) MOD10.

Precautions for Correct Use

The input variable is not allowed to omit. An error will occur during the compiling of the software if
the input variable is omitted. But the output variable is allowed to omit.
