Primitive procedures, or primitives, are built into Logo and are always present in the language. These are the basic Logo commands that are available when Logo is loaded. There are approximately 300 primitives in PC Logo for Windows. Use Logo Help to obtain a definition and examples of any Logo primitives once you have loaded Logo. To do so, type the word HELP (itself a primitive) and the name of a primitive you want to learn about. The Logo Help explanation for that primitive will appear. You can also access Logo Help via the Help menu or the Help button. Explanations and examples of all the primitives are also included in the Glossary.
