> Err, yes, but you do need to appreciate the underlying architecture of th=

Why would you *need* to appreciate it? I don't think many PC users=20
appreciate the finer details (or any details at all) of the x86 or x386=20
architecture (much less the horribly complex yet very successful=20
siblings that we use today).

I am now doing some work on a Cortex chip in C++. I am very familiar=20
with the ARM architecture and instruction set, but I don't feel any need=20
to dig into the Cortex instruction set. The authors of the GCC back-end=20
have done that, so I can go on with my work very effectively without=20
such knowledge. And later on I might switch to a PIC32, again without=20
first digging into the instruction set architecture.

I don't say that some knowledge of the asm level can't be beneficial,=20
but say that you *need* it is ridiculous.
