How does one go about seeing what RadAsm is sending out for assembly?
It depends on your assembler, RadAsm is an IDE, it does not do the actual assembly itself. In GoAsm you can modify the command line (project properties) to include /l which will instruct it to create a list file. Not sure what the switch in MASM is. If you simply want to examine the command line used to start the assembler include O in the project properties command for your assembler and/or linker.
