The Sum of the Numbers

Here is the program again:

' Add up the integers from START to FINISH
'
LET TOTAL = 0    ' TOTAL will hold the sum
LET START = -2
LET FINISH = 3
'
FOR COUNT = START TO FINISH
  LET TOTAL = TOTAL + COUNT
  PRINT COUNT, "has just been added to TOTAL which is now", TOTAL
NEXT COUNT
'
PRINT "The total is:", TOTAL
END

Here is what it prints:

-2 has just been added to TOTAL which is now -2
-1 has just been added to TOTAL which is now -3
0 has just been added to TOTAL which is now -3
1 has just been added to TOTAL which is now -2
2 has just been added to TOTAL which is now 0
3 has just been added to TOTAL which is now 3
The total is:  3
