I'm just starting to learn how to use vim, but I'm sure this
repetitive task can be managed efficiently using vim.
Though almost opaque in its terseness, my first attempt processes
the whole file into its respective bits in one pass:
:g/^/if (line('.')%6>2 || !(line('.')%6)) | exec '.w! >> '.(['D',
'', '', 'A', 'B', 'C'][line('.')%6]) | endif
or depending on the format, if the data lines are the only ones
with periods in them (identified by the regexp "^\d\+\.") then
that can be reduced to:
g/^\d\+\./exec '.w! >> '.(['D', '', '', 'A', 'B', 'C'][line('.')%6])
But is there a way to select certain lines or something similar?
I archived this email from Preben "Peppe" Guldberg (speaking of
whom, I don't remember seeing him on the list recently and hope
he's okay) which does something like what you describe in
response to a similar question:

You might be able to adapt it for your purposes.
Any suggestion to do it faster will be appreciated.
However, if you don't want to process each case by hand, you can
use my ugly stunt above that does the whole thing in one pass.
