软件包：ucblogo（6.2.1-2）

dialect of lisp using turtle graphics famous for teaching kids

This is the UC Berkeley implementation of logo written primarily by Daniel Van Blerkom, Brian Harvey, Michael Katz, and Douglas Orleans. This version of logo is featured in Brian Harvey's book _Computer_Science_Logo_Style, _Volume_1: _Symbolic_Computing_ (ISBN 0-262-58151-5). This version provides the following special features:

 - Random-access arrays.
 - Variable number of inputs to user-defined procedures.
 - Mutators for list structure (dangerous).
 - Pause on error, and other improvements to error handling.
 - Comments and continuation lines; formatting is preserved when
   procedure definitions are saved or edited.
 - Terrapin-style tokenization (e.g., [2 3] is a list with one member)
   but LCSI-style syntax (no special forms except TO).  The best of
   both worlds.
 - First-class instruction and expression templates.
 - Macros.
