:exec 'e \' | echo 'Hello World!'
The ":exe[cute]" statement wraps is operands the way ":echo" does, but
executes the resulting expression(s) as an Ex-command-line (separating
them by a single space, the way ":echo" does, into a single ex-command
if there are more than one expression) instead of displaying them, and
it can be followed by a | and more ex-commands on the same line. One
particularity of ":exe" (and ":echo", I think) is that if you want to
write a Vim-comment after it on the same line you must prefix it by |"
(vertical-bar double-quote) not just " (double-quote).
Best regards,
