Hi Ben,

these are ImageJ Macro commands. "call" allows you to call a static  
Java method from a macro. It must be lowercase, not "Call". You need  
no java programming to use it.

http://rsb.info.nih.gov/ij/developer/macro/functions.html#call

The macro command "call" is in ImageJ since version 1.37c.

---

By the way, another nice way of using the "call" command is saving/
reading preferences for a macro, for keeping them after closing and  
opening ImageJ. E.g.

   var par1 = parseInt(call("ij.Prefs.get",  
"myMacro.parameter1","0")); //read an integer parameter where 0 is  
the default

   function setOptions() {
     Dialog.create("my Macro Options");
     Dialog.addNumber("Parameter1", par1);
     Dialog.show();
     par1 = round(Dialog.getNumber());
     call("ij.Prefs.set", "myMacro.parameter1",toString(par1));
   }
