mem, thanks for the help and patience, but I have almost no idea how to use the utilities suggested in reply #2, or how to get any useful information out of the code in reply #6.
Remember that I have a total of about 10 hours of experience writing code of any type, so I'm not really understanding most of what you all are saying.
I was just curious how Loop() might be affected by how long a program is, in case I or someone wanted/needed it to loop at a known or controllable frequency.
So, I asked a co-worker to look at Blink and he was quite surprised that it took up much more than a few bytes of program space. Someone else then jumped in and said "make it print out a MAP file, that will have all the information you want". Hence the question that started this surprisingly long forum topic.
I await yet another attempt by some patient person to explain this in yet another way that my simple mind might understand it.
Thanks in advance!
