clear_fail

Post by mdosnov2016 » 10 Oct 2017 7:22

Dear all, how about the following error:

Type Action Description Filename Path
e229 Undeclared identifier 'exception::clear_fail/1' backend.pack

does anybody know where is located the predicate clear_fail ?

thanks in advance,
Michael

Look here in the prologSyntax package:

"C:\Program Files (x86)\Visual Prolog 7.5\pfc\prologSyntax\prologSyntax.cl"
"C:\Program Files (x86)\Visual Prolog 7.5\pfc\prologSyntax\prologSyntax.pro"

The HTML help file for VIP has a discussion of the prologSyntax package.

I have no knowledge beyond this.

There is no such predicate. Show the code that contains it then we may help writing something else.
