Hi Thomas,
as far as I can say you can't have global variables across different macro files, only within one macro file.
The way out would be using the ImageJ Preferences to store these values (as long as they are not arrays):
write:
call("ij.Prefs.set", "myMacros.myValue",toString(myVariable));
read (with default 999)
var myVariable = parseInt(call("ij.Prefs.get", "myMacros.myValue","999"));
Obviously, you don't need the 'toString' and 'parseInt' for Strings, and you should use parseFloat instead parseInt if you don't expect integers.
