Description

 • The recommended way to invoke usage is to use a double question mark (??). The recommended way to invoke example is to use a triple question mark (???).
 • When invoking info, usage, example, or related using the function call syntax, Maple keywords (reserved words) must be enclosed in back-quotes.  For example, info(quit) causes a syntax error. Use info(quit) instead. When using the double or triple question mark syntax, no quotes are required.
