     There is a better method available.  Check ACM Transactions on Modeling
and Computer Simulation, Volume 1, Number 2, April 1991, page 99-112.  There
is an article by  Shu Tezuka and Pierre L'Ecuyer titled  "Efficent and
Portable Combined Tausworthe Random Number Generators" which has some nice
mathematics in it.  They have a five line program in C which generates
random numbers with a period length of 10^18.  The program is easily converted
to Ada, and any other language.

     This reference is just one of 20,000 in my database of information on
all of the reusable source code available from government and university
laboratories.  The 1992 edition of the directory of the database if now
available for $149.  A postal address to me will get you a brochure.  A
contract from the government would get everyone on Internet a copy of the
database  :-)
