B. Forms

Consider the various ways sentences may be formed in natural human languages.
Rejoice that in BBL (and in Lisp) there are only two: the atom and the function.

B.1. The Atom

A lone symbol or value, nothing more. BBL returns the value or the value represented by the symbol.

If the atom is a value, BBL returns the same value.

Example:   47	a number
Example:   "Hi mom!"	a literal string
Example:   'A	a literal symbol

If it is a variable, BBL returns the value of the variable.

Try it! Go to the Listener and enter 47 into the command window and then return.
Then enter x into the command window and then return.
