I have been working on a stopwatch/countdown program, and I am having problems with the code.
Here's the problem:

Code:
```M→Z 20→A While Z≠0 A+1→A A-1→A A+1→A A-2→A A+1→A A-1→A If S=0:Then:M-1→M:Z-1→Z:60→S:End If A=0:Then:Then:S-1→S:20→A:End End:Disp "TIME UP!"```

I do have it output( it in the code, but when it has a minute left, it displays "TIME UP!". I want it to display it when everything equals 0.
What you want is startTimer aka. startTmr
That gives you accurate seconds!

The easy and modular countdown way (Uses A for total secs, Uses D for secs left; Destroys B and C; Put your code instead of the Disp D):

Code:
```Input "Secs: ",A startTmr->B checkTmr(B)->C While C<A A-C->D Disp D While A-C=D checkTmr(B)->C End End Disp "TIME OUT!" ```

The heavily optimized countdown oneliner (supply total secs in A; Destroys Ans and B):

Code:
```1:startTmr->B:While Ans:A-checkTmr(B:Disp Ans:End ```

The easy and modular stopwatch way (Uses B for elapsed secs; Destroys A), press any key to stop the stopwatch:

Code:
```startTmr->A Repeat getKey checkTmr(A)->B Disp B End Disp "BREAK!" ```
Also, if you want a counting up timer, this is a good way to do it. It is easily modifiable to go down as well.

Code:
```0->B Repeat Ans Disp B B+1->B startTmr->A:0 Repeat Ans+checkTmr(A getKey End End```

Countdown:

Code:
```10->B  ; Number of Seconds While B startTmr->A Repeat checkTmr(A:End B-1->B Disp B End```
Thank you for the count-up timer. While I do have that part, I just needed something for a countdown timer. Thanks!
