And a good one.  Cuz I thought of it too!  <g>

If this were something I'd doing on a regular basis and disk space was not
at a premium, I can see where the file you & I are thinking about would make
sense.  Still a problem of how to incrementally lay out 100 "bit" values.
I.e., programatically-speaking, what comes after binary '11010111'?

BTW, 100! = 9.3 e+153 = the number of any possible combination of a list of
100 elements.  Were you thinking of a different value?

I think I've got a plan.  It's being turned into a free-time exercise so I
won't play with this until an evening this week.

Thanks for throwing out ideas, Joe (and others)!
