KCL arrays can have up to 64 ranks.
When the value of the Common Lisp variable *print-array* (see Section 22.1.6 of the Common Lisp Reference Manual ) is nil, then bit-vectors are printed as #<a bit-vector>, other vectors are printed as #<a vector>, and other arrays are printed as #<an array>.
Common Lisp constants related to arrays have the following values in KCL.
array-dimension-limit = 16777216
array-rank-limit = 64
array-total-size-limit = 16777216
See Section 17.1 of the Common Lisp Reference Manual for their meanings.
