outputs TRUE if all inputs are TRUE, otherwise FALSE. All inputs
must be TRUE or FALSE. (Comparison is case-insensitive regardless
of the value of CASEIGNOREDP. That is, "true" or "True" or "TRUE"
are all the same.) An input can be a list, in which case it is
taken as an expression to run; that expression must produce a TRUE
or FALSE value. List expressions are evaluated from left to right;
as soon as a FALSE value is found, the remaining inputs are not
examined. Example:
MAKE "RESULT AND [NOT (:X = 0)] [(1 / :X) > .5]
to avoid the division by zero if the first part is false.
