I'd like to know the exactly filename of the program that is currently running on my NXT (e.g. MyProgram.nxj). Is there a method that can provide me the name? (I don't want to define the name programmatically because my program may exist with various names (e.g. MyProgram1.0.nxj, MyProgram1.1_test.nxj, MyProgram_workable.nxj) on the NXT).
