To run a separate script, use ":source" (q.v.), not ":exec".
The command
:exec "user config"
would execute the hypothetical command
:user config
but of course the ":user" command does not exist, so you get an error.
What ":exec" does is executing as an ex-command what ":echo" would have
displayed, given the same arguments. Notice that when you type an
ex-command at the command-line, Vim executes it as soon as you hit
<Enter> without waiting to see if you'll type zero or more whitespace
characters followed by a backslash.
Best regards,
Tony.
