- I am trying to implement disjunction, if-then, if-then-else and
- negation-by-failure according to ISO Prolog Draft of March 27, 1992, and I
- think there may be some mistakes in the examples. Can anyone comment?
-
- The mistakes (?) are:
-
- Section 7.8.7.2. This is examples of if-then. The second-last example
- appears to have a syntax error. I won't lose sleep worrying about that one.
-
- Section 7.8.8.2. This is examples of if-then-else. I just don't see how the
- stated behaviour of the last example can conform to the intended operation
- of if-then-else. This one I worry about.
-
- Can anyone help?
