# 2) Select the proper machine/compiler/OS section of code

#	a) Redrawing the bottom half of the screen when you

#	b) the highlighted row labels being trash when you
#		move between row 9 <-> 10

#		 -goto (or move) a few lines (or more) past the bottom
#		 of the screen, goto (or move) to the top line on the
#		 screen, move upward and the current line is deleted, the
#		 others move up even when they should not, check by
#		 noticing the rows become 2, 3, 40, 41, 42... (etc).
