Major Section: ARRAYS
Example Form: (aref2 'delta1 a i j) General Form: (aref2 name alist i j)where
name is a symbol, alist is a 2-dimensional array and i and j
are legal indices into alist. This function returns the value
associated with (i . j) in alist, or else the default value of the
array. See arrays for details.This function executes in virtually constant time if alist is in
fact the ``semantic value'' associated with name (see arrays).
When it is not, aref2 must do a linear search through alist. In
that case the correct answer is returned but a slow array comment is
printed to the comment window. See slow-array-warning.
