Not quite ... that is, not from the extremely basic level.  For example ... 
Assume that I have code that runs in another environment and now I want to 
compile it into an executable for my MCU.  I'm staring at a Windows Desktop 
... now what?  The <3.13.1 A Step by Step Introduction> refers to inline 
assembly language code.  Maybe a few words about where to start would be a 
good thing.

No ... those are widely available.  I'd expect information on how to use 
THIS compiler/linker/assembler, etc. though.

Well, that may, at least, lead to an answer to the question regarding the 
downloaded file set.  A clean system is never a problem.  I use removable 
(frame+tray) hard drives and always have at least one, for each system, that 
has never been present when attached to the internet or even the LAN. 
Sanitizing files acquired via the www is sometimes tricky, so they seldom 
see the "clean" drives.

Thanks for the comments, Frieder.  I'm not complaining.  I'm just lamenting 
that I've lost my way.  Perhaps I'm looking for that trail of bread crumbs. 
Being oriented to ASM and macros rather than HLL's for small code body, I 
haven't made 'C' a priority for MCU development.  However, as SiLabs, for 
example, has put its primary thrust into supporting the compilers (KEIL, 
SDCC) rather than ASM with its app-notes, etc, I'm taking another look.
