Since the program repeats the loop body again and again it does not stop after the third item but asks for another. Remember, if you want to stop it at this point, hit CONTROL-BREAK.

Indenting

Here is our program:

' Retail price calculator
' with 50% markup
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 * 1.5   ' compute and print out the retail price
LOOP  
END

The DO and the LOOP bracket the loop body. To clearly indicate which statements are in the loop body, indent each statement between DO and LOOP. This is as important to programming as grouping sentences into paragraphs is important to writing good English.
