Eddie, I do not understand how the NPV program is supposed to work. Please help me here, this is the code on your website:

Code:

2  PAUSE “NET PRESEN VALUE”
4  CLEAR    // clears all the variables
6  INPUT “CF0:”; N, “RATE:”; I
8  J = 1
10 INPUT “FLOW:”; F, “FREQ:”; K
12 FOR L=1 TO K: N = N + F/(1 + I/100)^J: J = J+1
14 NEXT L
16 INPUT “MORE=1: “; L   // enter 1 to enter more cash flows, anything else to end entry
18 PRINT USING “#############.##”; “NPV: “; N
20 END

As far as I can tell the program will sum up the discounted first K cash flows in line 12/14. Then the user is prompted with "MORE" so that second, third etc. cash flow and its frequency can be entered. For another CF the user is supposed to enter "1", or anything else to quit. But look at line 16/18: the program does not process the user input L at all. Instead it prints the NPV (for the first CF only) and quits.

I'd say there is a line missing here:

Code:

17 IF L=1 GOTO 10

Or have I overlooked something here?
