consult/1

consult(Filename)

Read facts and rules from a text file into the internal database.

Remarks

consult/1 reads facts and rules from the text file FileName (created by saving a database with the save/1 predicate) and asserts them in the internal database.

If the file contains any syntactic errors, consult/1 generates an error.

Example

consult("DD.DBA").

--- Contents of "DD.DBA" might be ---

p1(1,'a',44.44,"PC","Prolog",[1,2,3,4])

p1(2,'b',-4.444E-98,"---","++++",[])

p2(88)

p2(99)

NOTE:

G.I.S. Prolog allows programs to consult other programs while being... consulted! Using the single-argument/arity ":-" operator inside a program instructs the interpreter to execute a series of goals (after the ":-") which may include consulting other files (which may -in turn- consult other files, ad.inf).
