; Program Description: 
; Program 2:
; Write a program to calculate Fibonacci numbers.
; Display the program title and programmer’s name. Then get the user’s name, and greet the user.
; Prompt the user to enter the number of Fibonacci terms to be displayed. Advise the user to enter an integer in the range [1 .. 46].
; Get and validate the user input (n).
; Calculate and display all of the Fibonacci numbers up to and including the nth term. 
; The results should be displayed 5 terms per line with at least 5 spaces between terms (I failed to do this and my comments are mentioned below)
; Display a parting message that includes the user’s name, and terminate the program.
; Tried extra credit: do something incredible. Made a greeting window, changed color of program title, and changed the color of the printout for better viewing for the user
 
 
 
;defined constant for upper limit of Fibonacci terms
FIBSTERM = 47
