I would go for just a simple
set(beamsize,5).

Why not write a simple loop in your program, reading terms from the file?
That's how I implement data files. For simple facts, you just assertz()
the term you get from the file.

If you want to allow user-defined predicates or something, you may have to
inspect the term more closely before acting on it (if read() understands
the :- at all, I don't know). Anyway, shouldn't be too complex to
implement "manually".
