Comments

This function should not be called within a user-defined function which has no arguments, if that user-defined function might be called multiple times within a single block (rule). This is because functions with no arguments are actually evaluated only once per rule and return this same result on each function call during the execution of that block.

This is not a very good random number generator, but is implemented in this way for historical reasons. If ResetRanDev() has not been called before this function, then the results are unpredictable.
