OMG, why in the world do you need a field that 
will store the distance from us to the Andromeda 
galaxy in inches?  Just call CLOCK  as a seed 
value, it goes down to a tenth of a second, which 
might do it, I always used this in a loop to 
create random file names until flabelinfo didn't 
fail on the file name.  I seem to remember some 
random seed generator, but I can't remember the 
language or platform now, but I thought it was back on a series III
