Thanks, I am reading "Learning Prolog Now" (Patrick Blackburn, Johan Bos and
Kristina Striegnitz).
This first DCG sample(attached mydcg.P) was run OK on XSB:
s --> np,vp.
np --> det,n.
vp --> v,np.
vp --> v.
det --> [the].
det --> [a].
n --> [woman].
n --> [man].
v --> [shoots].

How can I use DCG with Flora-2?
File.P must contain only Prolog/HiLog codes?
File.flr must contain only Flora-2 code?
Thank you for your help.
