We are grateful to Bart Demoen, KU Leuven for participation in discussion on ISO compatibility and body conversion of Jekejeke Prolog 0.9.1.

We would like to thank Ulrich Neumerkel, Technische Universität Wien, for testing the syntax and the console of Jekejeke Prolog 0.9.1 and handing us around 50 findings.

Further thanks go to Jos De Roo, Agfa Healthcare for providing us a critical test case for the indexing and for meta-arguments of Jekejeke Prolog 0.9.7.
