I was looking at the ASM listing that is generated for human use, and it wasn't annotated, so I made some changes to SimpleIDE and hello.c generates this now:
Would you like me to commit this change?

The SimpleIDE is generating .asm files for the listings when the user asks for "Show Assembly" from the project manager.
I've also added "Show Map File" for the main program file and looking at usage, etc....
