Hi Freeman, > I understand the above and below but not this let ((rand (random 100))) > Put in your form: (let ((rand (random 100))) ...)
Here are the thoughts of a Scheme newbie — hopefully they are correct! =) Working from the inside out: The first set of parentheses is needed to encapsulate the random number procedure/expression: (random 100) The second set of parentheses associates that procedure/expression (a.k.a. result) with a variable [to be set using Let]: (rand (random 100)) The third set encloses the "complete set of [Let] variables": ((rand (random 100))) The fourth set [in Harm’s form] is for the Let procedure/expression itself: (let ((rand (random 100)))) Hope that helps you understand it!
