You could get all of this information out of a file-based output of sysgen,
listing all the various i/o devices. Once it's in a file, you could write a
program to parse the output to seek out and reformat it into tables designed
for the easy retrieval of whatever information you're interested in.

That actually wouldn't be much more trouble than calling one of the
DBINFO-like intrinsics that generates long lists.
