(j3.2006) RANDOM_INIT question

[Bill Long]

Suppose the program calls RANDON_INIT with the REPEATABLE argument having the value false.   In this case, does the concept of a ?seed? have any meaning?  Would a call to RANDOM_SEED have any effect for a non-repeatable generator?  More particularly, would it be conforming to use the RDRAND instruction on recent Intel chips to create the random number returned by RANDOM_NUMBER,  and just ignore the seed value set by RANDOM_SEED?

Cheers,
Bill
