     The first non-comment line, "set nocompatible" puts you in
"enhanced" mode.  (I call it 'nocompatible' mode.)

     I do not think you need my system vimrc file.  Its only purpose is
to set the PATH environment variable when Vim.app is started from the
Finder.  If you are starting from a shell, then vim will inherit the
shell's current PATH variable.

     You are welcome.  I still suggest that you look at
$VIMRUNTIME/vimrc_example.vim .  It contains many recommended settings,
and it is well commented.
