[bp-users]Looking for documentation a list of prolog flags for B-Prolog

[Douglas R. Miles]

Hi,

I am trying to find in documentation a list of prolog flags

I can't gleen them from current_prolog_flag/2 since it it gives
deterministic exit:

| ?- current_prolog_flag(X,Y),write(X=Y),nl,fail.
unknown=error
no
| ?-


Thank you,

Douglas
