For example, a delay between 1 and 10 (inclusive) is equivalent to 10 or 15.6 on most Windows 2000/XP systems. To achieve a shorter delay, see <a href="#ShorterSleep">Examples</a>.</p> <p>The actual delay time might wind up being longer than what was requested if the CPU is under load. This is because the OS gives each needy process a slice of CPU time (typically 20 milliseconds) before giving another timeslice to the script.</p> <p>A delay of 0 yields the remainder of the script's current timeslice to any other processes that need it (as long as they are not significantly lower in <a href="Process.htm#Priority">priority</a> than the script). Thus, a delay of 0 produces an actual delay between 0 and 20ms (or more), depending on the number of needy processes (if there are no needy processes, there will be no delay at all). However, a <em>Delay</em> of 0 should always wind up being shorter than any longer <em>Delay</em> would have been.</p> <p>While sleeping, new <a href="../misc/Threads.htm">threads</a> can be launched via <a href="../Hotkeys.htm">hotkey</a>, <a href="Menu.htm">custom menu item</a>, or <a href="SetTimer.htm">timer</a>.</p> <p><strong>Sleep -1</strong>: A delay of -1 does not sleep but instead makes the script immediately check its message queue. This can be used to force any pending <a href="../misc/Threads.htm">interruptions</a> to occur at a specific place rather than somewhere more random.
