  A notice to Kire: the command that you given isn't what I want. I need a command that only makes the programm to sleep, not to crash!

  @HappyProgrammer11 You don't stop the program from working. Codea runs in a constant loop and the way you stop something from executing is to not execute its function. You use an if statement to control when a function is called. If you have instances of a class that draws several things on the screen, then use the if statement and some variable to call or not call those instances.

  Here's an example to show or not show a sprite

  function setup()
  end
  
  function draw()
      background(40, 40, 50)
      fill(255)
      text("tap screen to show or not show a sprite",WIDTH/2,HEIGHT-100)
      if show then
          sprite("Planet Cute:Character Horn Girl",WIDTH/2,HEIGHT/2)
      end    
  end
  
  function touched(t)
      if t.state==BEGAN then
          show=not show
      end
  end

  So you want the program to be in some pause/standby?

  Again a personal message to Kire: Yes, but I want it to be in the standby for a fixed amount of time.

  to pause a program for X seconds, try this

  function pause(X)
      paused=ElapsedTime+X
  end
  
  --then set up your draw program like this
  
  function draw()
      --don't draw anything if paused
      if paused then 
          if ElapsedTime<paused then return else paused=nil end
      end
      --your other draw code goes here
  end
  
  --then to pause your program for 5 seconds, write this line
  pause(5)

  @Ignatz Please, tell me how to use this inside a loop or another function instead for the draw function.

  You have to tell your draw function not to draw during a pause.

  That's what my code does.
