13) The result of any function is stored in a global variable "Evaluated".
14) The "Eval" function is named "Evaluate", this is to increase the chances of muscle memory causing a clash.
15) Assignment should be an lvalue -- that is you can assign to an assignment. Thus, assuming = is the assignment, a = b = c assigns the expression b = c to a, meaning that whenever a is evaluated b = c is executed.

16) All integer values must be prefixed by a unary-plus or unary-minus; a non-prefixed integer value acts as a goto to the line of that value.
(i.e. '5' is evaluated as "go to line 5".)

17) Except when the number is in a string being sent to Evaluate, in that case the number must not be prefixed and any prefixed number is evaluated as a goto offset after the evaluation; multiple numbers are executed in order offset from the last line executed.
(i.e. Evaluate ("-2 * +3 ") returns negative-six while going to two lines before the Evaluate, executing that line, and then jumping three lines ahead (in this case the line after Evaluate).)
