Mostly for reasons of poor eyesight and incoordination.  (= the brain
doesn't get all the information it needs, and the fingers don't move
the way the brain intended them too.)

I think for sectors and cylinder values (the -s option) that is true.
(But I sure wish the default for NetBSD's fdisk would be a single and
active NetBSD partition, and not DOS of all things.)

It seems clear that fdisk was intended to be run interactively.  In my
case, unfortunately, that means more time required, more care, and more
chance for error.

For me, scripts are the way to go.  Once it's finally done correctly,
I get the expected results, no surprises.

There's a LOT missing from the fdisk and disklabel documentation.
(I'm still stumped on the cylinder alignment business, but I'll wait
for that until I get back to old scsi drives on sparc -- the next
project.)

Thanks for all your help.  I think I've made some real progress.
