Loading the Prolog code

Prolog code (source or object code) can be loaded by submitting normal Prolog load predicates as queries. Note that SICStus uses slashes '/' in file names where Windows uses backslash '\'.

Example:

PrologQueryCutFail("load_files('d:/xxx/myfile')")

To facilitate the location of Prolog files, two clauses of user:file_search_path/2 are predefined:

app

identifies the directory path of the Visual Basic project or the applications executable.

That is, you can load the file myfile located in the same directory as the project/executable, issuing the query
PrologQueryCutFail("load_files(app(myfile))").

vbsp

identifies the directory path of the vbsp.dll file.

That is, you can use the query PrologQueryCutFail("load_files(vbsp(myfile))") to load the file myfile if it is located in the same directory as vbsp.dll.
