Re: monte carlo and distribution functions

Sri -
You've got it backwards for LRM 2.1, which says "seed shall be a reg,
integer, or time variable."

LRM 2.2 extended it to allow parameters in order that the random
functions could be used in parameter initialization.

(We did make some changes to the wording, both in AMS LRM 2.2 and
in 1364-2005, so that "seed" is described as an "inout argument"
to the system functions, instead of "inout parameter" which 
doesn't make any sense.)
