Type a number
? 100
6% of the number is 6

Same Statements, Executed Again

Here is the example program, again:

' Example of a loop
DO                       
  PRINT "Type a number"
  INPUT NUMBER
  PRINT "6% of the number is", NUMBER * 0.06
LOOP                     
END

The statements between DO and LOOP have each been executed once. The variable NUMBER has the value 100 in it:

NUMBER

100

Now the statements inside the loop start again with the first statement after DO:

• For a second time, the PRINT statement prints "Type a number".
• For a second time, the INPUT statement gets a number to put in the variable NUMBER.
  • Say that the user typed in 50. The number 50 will replace what was previously in the variable.
• For a second time, the second PRINT statement prints "6% of the number is" and then computes and prints 50 * 0.06.
• The LOOP statement marks the end of the loop.

At this point, variable NUMBER now has the new value of 50 in it:

NUMBER

50

The monitor now shows:

Type a number
? 100
6% of the number is 6
Type a number
? 50
6% of the number is 3
