[Question] 2 things at same time

Hello!
I have made a program, more like a desktop, with shortcuts to my programs using a menu(as seen here). At the top of the desktop there is a hour bar who uses os.time. It actually works, but the hour only updates when i press a key(arrow up/arrow down). My doubt is, can I make the hour update, while, at the same time, the program waits me press a key?

If is there any english error, sorry, I'm still training my english.

while true do
local x, y=term.getCursorPos()
term.clearLine()
if n==1 then write(">YES< NO") else write (" YES >NO<") end
term.setCursorPos(x, y)
a, b=os.pullEvent()
while a~="key" do a, b=os.pullEvent() end
if b==203 and n==2 then n=1 end
if b==205 and n==1 then n=2 end
if b==28 then print("") break end
end

In the code, it has:
a, b=os.pullEvent()
while a~="key" do a, b=os.pullEvent() end
if b==203 and n==2 then n=1 end
if b==205 and n==1 then n=2 end
if b==28 then print("") break end
end


That means before it continues, it waits for you to press a button, so it stops the timer and everything else

Please, use code tags.

You can use timers:

local updateTimer = os.startTimer()
...
<inside your loop checking for keys>
if event == "timer" and param1 == updateTimer then
 updateYourHourBar()
 updateTimer = os.startTimer(1) -- Update it every second.
elseif event == "key" and blah then
...
end

Something like that.

I can't guess how you've done your code though, so you'll have to post it if you want more informative help.

You can use a timer to do that:

local timer = os.startTimer(1)
while true do
  local evt, arg = os.pullEvent()
  if evt == "key" then
	do_menu(arg)
  elseif evt == "timer" then
	update_timer()
	if arg == timer then
	  timer = os.startTimer(1)
	end
  end
end

So it updates the timer each second, and your menu works at the same time.

Edit: oops, too late :o/>/>

The method I described should be able to do what you want, but it'll render the whole screen again. That's not really a problem, though.
