This is difficult to do, even for us! To help, under Project..Settings..Fortran..Listing Files enable the Source Listing and then check the Machine Code box. (This is not the same as an assembler file.) When you recompile, look at the .LST file in your Debug or Release folder. It will contain an annotated machine code listing that may, in some cases, indicate what variable is used in a particular instruction.
