Revise paste MDC_Upper_Hall_Cut_Place

-- This program digs a mining stairs with a five levels down per filght of stairs
-- Pastebin code = "TaFFELNp"; Pastebin name is "MDC_Upper_Hall_Cut_Place"

-- This program assumes that you place the turtle down on the forward end of the upper pad (a 2 stone x 2 stone)
-- Place coal into Turtle slot #1 to assure adequate fueling
-- Place stone into Turtle slot #2 and #3 to assure adequate placement resources
-- This program begins by asking you to indicate whether you want to cut an upper hall (H response) or stairs (S response)

    print( "Your fuel level is less than 200; refueling with 240."      )
