#  The Program will display a menu that a user can select an option from and get a little note ;)

#
#  Write a script that will do the following:
#      Provide a comment section at the top of the script,
#      with your name, the date, and the purpose of the program.
#
#      Use the select loop to produce a menu of foods.
#      Produce output to resemble the following:
#        1) Steak and potatoes
#        2) Fish and chips
#        3) Soup and salad
#        --------------------------
#        Please make a selection. 1
#          Stick to your ribs
#          Watch your cholesterol.
#          Enjoy your meal.
#        --------------------------
#        Please make a selection. 2
#          British are coming!
#          Enjoy your meal.
#        --------------------------
#        Please make a selection. 3
#          Health foods…
#          Dieting is so boring.
