You can look at $VIMRUNTIME/macros/editexisting.vim for examples.

But I think the easiest solution, since you're loading stuff from an external program, would be to always use the same Vim server for that external program. Launch Vim initially with a specific server name and set up your program to use that server name rather than the default.

--remote does not pass any of the -c commands on to the new server. --remote causes the Vim you invoke to use all the -c commands itself and then pass the file on to the other Vim server.

You may need to use the --remote-expr or --remote-send flags instead of (or in addition to) the --remote flag. Also see the remote_expr(), remote_peek(), remote_read(), and remote_send() functions for use within an already-running Vim.
