Subject: Derived Procedures in ISO 10179 From: Andreas.Saremba@xxxxxxxxxxx (Andreas Saremba) Date: Wed, 15 Jul 1998 22:39:50 +0200 |
Has anybody undertaken to check the correctness of the definitions for the derived procedures given in the DSSSL standard? I needed one of them today, copied the definition - and found it didn't work. Here it is (from 10.2.2, pages 135 f.) (define (node-list-head nl i) (if (zero? i) (empty-node-list) (node-list (node-list-first nl) (node-list-head nl (- i 1))))) This is an obvious error - the "nl" in the last line has to be replaced by "(node-list-rest nl)". (Ok - they couldn't test it in 1996.) I understand the DSSSL Documentation project is working on documenting these things, but I havent't found this one in their material. It would be very helpful to have all these procedures collected for reuse in one's own scripts, and I would be willing to help in this effort, but certainly not until I'm confident that I'm not re-enventing the wheel.
