22.1.3.15 Printing Other Vectors

If *print-array* is true and *print-readably* is false, any

vector other than a string or bit vector is printed using general-vector syntax; this means that information about specialized vector representations does not appear. The printed representation of a zero-length vector is #(). The printed representation of a non-zero-length vector begins with #(. Following that, the first element of the vector is printed.

If there are any other elements, they are printed in turn, with each such additional element preceded by a space if *print-pretty* is false, or whitespace_1 if *print-pretty* is true.

A right-parenthesis after the last element terminates the printed representation of the vector. The printing of vectors is affected by *print-level* and *print-length*. If the vector has a fill pointer, then only those elements below the fill pointer are printed.

If both *print-array* and *print-readably* are false,

the vector is not printed as described above, but in a format (using #<) that is concise but not readable.

If *print-readably* is true, the vector prints in an implementation-defined manner; see the variable *print-readably*.
