First, you may have the wrong version of PGasu.pl from cvs. You should
get the one in system/courseScripts . That one should not have a
problem with list_random.
Second, I should probably change it to take the syntax I gave above, but the syntax for using it is really:
ANS( pc_evaluator([[str_cmp("zero"), 1, ''], [str_cmp("0"), 1, ''],
[str_cmp("nothing"), 1, ''], [str_cmp("nothingness"), 1, ''],
[str_cmp("zilch"), 0.5, 'For full credit, try using a less colloquial
The third arguments are comments which can be displayed. There is also an extra set of brackets this time.
