// Queued Macros
//
// This macro set demonstrates how to ovoid overlapping 
// macro execution by setting the "QueueMacros" option.
//
// Steps to test:
//
//    1. Press ctrl-i (Macros>Install Macros) to install
//        the macros. The Log window will open.
//    2. Activate the ImageJ window.
//    3. Type "12" to run both macros.
//    4. 1-2-3 is displayed in the Log window, indicating
//        that the macros ran in succession.
//
// Change 'true' to 'false' in setOption("QueueMacros", true), 
// repeat the first three steps, and notice that 1-3-2 is displayed 
// in the Log window, indicating that the macros ran concurrently.
//
// Note that the "QueueMacros" option does not work with macros
// using function key shortcuts in ImageJ 1.41g and earlier.

var xx = setup(); // runs when macros are installed
function setup() {
     setOption("QueueMacros", true);
     print("\\Clear");
     return true;
  }

// macro with keyboard shortcut of "1"
macro "aa [1]"{
	print(1);
	wait(1000);
	print(2);
}

// macro with keyboard shortcut of "2"
macro "bb [2]"{
	print(3);
