Starting the Loop

So now the program is about to start repeating the statements in the loop body. Memory looks like this:

Look at the looping part of the program:

' Retail price calculator
' with markup entered by the user
PRINT "Enter the amount of markup in percent"
INPUT MARKUP
LET RATE = 1 + MARKUP / 100
DO     

  PRINT "Enter wholesale price"            ' ask the user for the wholesale price 
  INPUT WHOLESALE                          ' get the price, put it in a variable
  PRINT "Retail price:", WHOLESALE * RATE  ' compute and print out the retail price

LOOP
END

The loop works as it did in the previous program, except that now the multiplication involves two variables. Here is what the screen might look like:

Enter the amount of markup in percent
? 10
Enter wholesale price
? 100
Retail price: 110
Enter wholesale price
? 200
Retail price: 220
Enter wholesale price
? 50
Retail price 55
Enter wholesale price
?

As before, end the program by typing CONTROL-BREAK.
