Hi all, There is an updated test script available at: http://www.xs4all.nl/~thospel/golf/tpr04c.pl It's not on the TPR(0,4c) page yet, but should be fairly soon. It includes some more test cases for Factorial. It also allows you to run tests for individual holes by giving them as command line arguments (e.g. "tpr04c.pl factorial" will only run tests for factorial). Happy golfing! -- Mike -- Michael W.
