Fwd: Re: User-defined functions (correction of my last post)

[Michael Cammer]

I take back what I said.  This with the same names works fine.  Maybe it's
the version of ImageJ.  I'm still using 1.37j at my desk.

var someText = "";

macro "test" {
   test();
   print(someText);
}

function test() {
   someText = "Here is some text";
}
