By the way, i should say in my defense that the reason the improvements
did not work was (I believe) caused by the following problem with Unix.

If you try to execute 

     ls oeis* | ...

and there are too many files oeis*, you get an error message

     Arg list too long

I didn't actually see this message, because the ls command is buried deep
in the shell scripts, but I assume that is what was causing the "lookup"
command to fail.
