UCBLogo
UCBLogo, also termed Berkeley Logo, is a programming language, a dialect of Logo, which derived from Lisp. It is a dialect of Logo intended to be a "minimum Logo standard".
It has the best facilities for handling lists, files, input/output (I/O), and recursion.
It can be used to teach most computer science concepts, as University of California, Berkeley lecturer Brian Harvey did in his Computer Science Logo Style trilogy. It is free and open-source software released under a GNU General Public License (GPL).
Logo was designed in spirit of low threshold and no ceiling, which enables easy entry by novices and yet meet the needs of high-powered users. UCBLogo has a rudimentary graphical user interface (GUI), so several projects exist that provide a better interface. MSWLogo and its successor FMSLogo, for Microsoft Windows, are commonly used in schools in the United Kingdom and Australia.[citation needed] For input/output (I/O), text may be written to the command window (output stream) using print and to the graphics window using label.
Animations require both the ability to draw and to erase shapes. The process is the same, except that in the former, a line is deposited on the display device and in the latter a line is removed. Using the turtle analogy, the turtle's pen must paint, and the turtle's pen must erase. The turtle can be set to erase anything below it, using the command PENERASE (PE), while the pen can be set to start drawing again with the command PENPAINT (PPT), in UCBLogo.
The analogy of a turtle with a pen attached to its tail is often used. The turtle's pen can be lifted and lowered, thus drawing a rudimentary dotted line.
An example code:
There are three data types in UCBLogo: the word, the list, and the array (a number is a special case of word). The interpreter detects the datatype by context; there is no static typing.
