Re: [eclipse-users] Conditional jump out of loops

My solustion is that a) Prolog is not Java, b) In Java, program that
uses break inside a loop can be transformed into program that doesn't
use break, c) There are many languages that don't have break
functionality, and people somehow write programs using these languages,
including loops.

To the original poster: If you feel that you need "break" in the middle
of a "loop" when programming in Prolog, then most likely you are trying
to write Java program in Prolog
