:maximum-lengthfrom the header of an array
Major Section: ARRAYS
Example Form: (maximum-length 'delta1 a) General Form: (maximum-length name alist)where
nameis an arbitrary object and
alistis a 1- or 2-dimensional array. This function returns the contents of the
:maximum-lengthfield of the header of
alist. Whenever an
aset2would cause the length of the alist to exceed its maximum length, a
compress2is done automatically to remove irrelevant pairs from the array.
Maximum-lengthoperates in virtually constant time if
alistis the semantic value of
name. See arrays.
