Counting Balloons

Here is a program skeleton:

' Draw 10 Red Balloons
SCREEN 12     ' start up graphics
COLOR 4       ' set the pen color to red
'
LET BALLOON = 1
DO WHILE BALLOON <= 10
  ..... draw the balloon ....
  LET BALLOON = BALLOON + 1
LOOP
'
END

The idea is:

To draw 10 balloons, count each balloon as it is drawn. Start the count at 1 and stop it at 10.

The program does just that by counting from 1 to 10:

• The first number (1) goes in the initializing LET statement.
• The last number (10) is tested for in the DO WHILE statement.
• The amount to increase the number each time (1) is in the LET statement in the loop body.
