I figured it out!!
Using the "Windows Command line.
First I copied the "avr-objdump.exe file from the location where the "Arduino" compiler is located to the location where the Sketch I wanted tested is located.
Second, I copied the sketch.elf file from the location where the compiler stores the file to the directory where I store the sketch I wanted tested is located.
Using the "Windows command line" I typed in "avr-objdump -t *.elf>dump.txt" (return)
The avr-objdump generated a text file (dump.txt) and put it in the sketch directory for me.
The objdump program generated a wealth of information for me including memory locations of all of my data structures. That was exactly what I was looking for.
The information presented above is for anybody else trying to use the AVR program.
Many thanks for all of your help!!
