It was, I believe the ``first'' LOGO licensed by the MIT lab. It allowed connection to a floor turtle and had (has) some routines to do music. Its TRACE was a good feature. Though I did not use Apple LOGO very much at all it did seem to have one very good primitive built-in: it is possible to PACKAGE a group of procedures and to then BURY the package, in a practical sense, from user modification. This would be useful if you wanted to extend the range of primitives with a package of pseudo- primitives which would then never appear when workspace procedures were listed, etc. I no longer teach, but my kids play with LOGO. Another excellent book that I would recommend is by Peter Ross (U. of Edinburgh) called ``LOGO Programming'' [Addison-Wesley 1983 ISBN 0-201-14637-1 (paper)]. It covers the usual turtle graphics, and also words and lists, and includes examples of how projects can be carried out with suggestions for other projects. Sprinkled throughout are notes to teachers on the philosophy of LOGO, what concepts are being illustrated by particular examples, and discussions of various algorithmic approaches. That is, the book is aimed at LOGO programmers of various ages, and includes discussions that can be appreciated by computer scientists of varying experience. Allen Brown
