Major Section: ARRAYS
Example Form: (aref1 'delta1 a (+ i k)) General Form: (aref1 name alist index)where
nameis a symbol,
alistis a 1-dimensional array and
indexis a legal index into
alist. This function returns the value associated with
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,
aref1 must do a linear search through
that case the correct answer is returned but a slow array comment is
printed to the comment window. See slow-array-warning.
