Simplest timer (just curious about how someone else would do this)

[Newb]

I've made a simple code to beep as an alarm clock on a time I decide (to take pauses while programming) and I would like to know if anyone else has faster, shorter, more intelligent or less expensive (in terms of resources used) solutions. Anything better or different is accepted. Just curious.

Dim $time[2]=[TimerInit(),TimerDiff($time[0])]
While $time[1]<3000
$time[1]=TimerDiff($time[0])
Sleep(100)
Wend
Beep(2400,2000)

Here is mine. One thing is, $time[1] is used too soon (but autoit makes it run, so i left it there), the correct version should be like this

Dim $time[2]=[TimerInit()]
$time[1]=TimerDiff($time[0])
While $time[1]<3000
$time[1]=TimerDiff($time[0])
Sleep(100)
Wend
Beep(2400,2000)

I even tried to make a version with inputbox but autoit mess it up big time, as always with converting from string to numbers (always had problem doing it smooth...) to compile into an exe for future use, so I'll keep it running from Scite.

This was the inputbox version:

Dim $time[3]=[Number(InputBox("Timer Set","How many seconds you want the alarm to beep?")),TimerInit(),TimerDiff($time[0])]
While $time[2]<$time[0]*1000
$time[2]=TimerDiff($time[1])
Sleep(100)
Wend
Beep(2400,2000)

Tried to fix it in 2023090239 different ways. Never worked, timer still sounds instantly.

(Put Int instead of number, Put Number/int in the while instead of the array, Tried to declare arrays subcripts separately etc. etc.) I did anything that came up in my mind and I wasn't able to find a solution.

So another question would be, why autoit hates numbers, or why autoit numbers/int conversion does the work but this still doesn't work?

Thank you all, expecially MVP, for being as awesome as you are.

Try this out for size:

NOTE: see comments in the script

Global $time[3] = [InputBox("Timer Set", "How many seconds do you want wait until the alarm beeps?"), TimerInit(), ""] ; changed the prompt to reflect what you're actually setting
$time[2] = TimerDiff($time[1]) ; $time[1] doesn't hold a value until you declare it, so you can't set the TimerDiff in the same declaration as the array above
While $time[2] < ($time[0] * 1000)
    $time[2] = TimerDiff($time[1])
    Sleep(100)
WEnd
Beep(2400, 2000)

Ok thanks, much appreciated.
