I'm currently in University on my Co-op term as a COBOL programmer for host
systems (zOS). I have a few basic questions regarding the zArchitecture that I
can't seem to elicit answers to from my co-workers. The questions are as

At least for question 1, go find a manual called the "Principles of
Operations". You can search the IBM website by that name and then download
it to read.
The BCP is nothing more than the core MVS components. MVS is comprised of
many subsystems, each doing a specialized function. The "Kernel" i

I always called the manual "z/Arch POP".
I picked that up from a Canadian IBM'r.
But, most didn't understand what that meant.
When in doubt.

I strongly disagree. Some good programmers are arrogant, but then again so are

Ron, I don't pretend to be expert in channel protocols, but from what I
read the FICON protocols are quite different from ESCON. I've read that
