7 Summary and Recommendations     continued...

We note that FORTRAN 90 will obviate many of the impediments to a portable implementation of random number generators, as: (1) it allows arbitrary precision in numbers, which can be made large enough to eliminate overflow and problems with a sign bit, and (2) it has embedded in the language functions to return the date and time, which now are system calls and vary from system to system. Moreover, a random number generator intrinsic function exists as part of the language, and it may be quite good (although it will have to be tested thoroughly by the Monte Carlo community before gaining universal acceptance).
