1. Define functional form, simple list, bound variable and referential transparency.

Functional form : one that either takes one or more functions as parameters or yields a function as its result. 

Simple list : A list that does not include sublist.
Bound variable : A bound variable is a variable which never changes in the expression after being bound to an actual parameter value at the time evaluation of the lambda expressions begin. 

Referential transparency : A state where execution of function always produces the same result when given the same parameters.

1. Define exception, exception handler, raising an exception, disabling an exception, continuation, finalization, and built-in exception.

Exception : any unusual event, erroneous or not, that is detectable by either hardware or software and that may require special processing.

Exception handler : a code unit which processes an exception.

Raising an exception : When a event associated with an exception occurs

Disabling an exception : Ignoring a certain hardware-detectable exceptions.

Continuation : Control transfer to somewhere in the program outside of the handler code or program might terminate .

Finalization : ability to complete some computation regardless of how subprogram execution terminates.

Built-in exception : Exception that is not made by the user, but rather comes as default.

1. What are the three characteristics of subprogram?

• Each subprogram has single entry point 
• The calling program unit is suspended during the execution of the called subprogram, which implies that there is only one subprogram in execution at any given time. 
• Control always returns to the caller when the subprogram execution terminates
