In the future please start two separate threads if you have two

Sorry! They were linked in my mind because they happen in the
same function -- indeed the output from the one is used as the
file basename for the other. I'll try to remember that what seems
connected to me not necessarily is so out of my context!

The system() function will return (as a string) the output of
an external command without modifying any text in buffers.
After system() runs the error code returned is in
v:shell_error.
No way to get stderr?

[snip]
Each window inside Vim is assigned a number. Window numbers
start at 1 in the topmost leftmost window and always increase
as you go down or right. So in this example 'a' will have
window number 1, b will have 2, and c will have 3.
I had a thinko wrt two horizontally split windows to the right
of a vertical split. It's clear to me now that top right
necessarily comes before bottom right. Yuck, my tabs look like
comic-book pages sometimes...
To open a specific file in a specific window, you will need 2
or 3 steps:
1. Jump to the desired window
2. Open the file
3. [optional] jump back to the previous window
For example, to edit "myfile.txt" in window 3 and then return
to the previous window:
3wincmd w | e myfile.txt | wincmd p
You can build such a string with a few :execute commands if you
need to calculate file names or window numbers from variables.
All clear now, except for how to capture stderr. Thanks!
