NAME

contextTF.pl - Imlements contexts for true/false problems.

DESCRIPTION

Implements contexts for string-valued answers especially for matching problems (where you match against T and F).

        Context("TF");

You can add new strings to the context as needed (or remove old ones) via the Context()->strings->add() and Context()-strings->remove() methods.

Use:

        ANS(string_cmp("T","F"));

when there are two answers, the first being "T" and the second being "F".
