I think that the following will create a file containing one million
spaces (and *no* carriage-return after them). I haven't tested it. It
mixes ex-commands and normal-mode commands. It assumes that the current
file is not modified. It will fail (with an error) if the required
features are not compiled-in. <Space> and <Esc> are one keypress each.
It assumes that ^ is a valid character in a filename, which is true
under Unix/Linux; I don't know about Windows.

:enew
:setlocal virtualedit=all binary noeol
:set undolevels=0 nobackup nowritebackup
1000000|
i<Space><Esc>
:saveas 10^6spc.txt

For a million 'a' instead, add

:s/ /a/g

before the :saveas but that :substitute operation may be costly.


Best regards,
Tony.
