That's not true. On Windows, at least prior to Vim 7.4, _vimrc _is_ part of the Vim installation. MyDiff() is/was part of the standard _vimrc installed under C:\Program Files\Vim (the XP path). I've been bitten by this before, where I made changes to that _vimrc, then updated to a newer version of Vim but excluded _vimrc from the update and couldn't execute diffs because the new version of Vim had changed MyDiff(). Now I save my old _vimrc, let the installer create a new _vimrc, and check the differences. I've also stopped using that system _vimrc and use ~/_vimrc instead, but I still check for changes to the system _vimrc. Regards, Gary -- -- You received this message from the "vim_use" maillist.
