Hi Thorsten,

you can write to the Preferences file in a macro. It is not obvious,
because it uses a call to the respective Java function.
The prefs file saves the values as Strings, but you can convert them
from/to numbers:

//write:
   call("ij.Prefs.set", "myMacros.myValue",toString(myVariable));

//read (with default 999):
   myVariable = parseInt(call("ij.Prefs.get", "myMacros.myValue","999"));

(mind possible line breaks introduced by the mailer)

This will keep the values when you restart ImageJ, but you could have
the StartupMacros reset the value to some default. For this, have an
"AutoRun" macro in the StartupMacros:

macro "AutoRun" {
   defaultValue = -1;
   call("ij.Prefs.set", "myMacros.myValue",toString(defaultValue));
}

Michael
