11 * mark.c: functions for setting marks and jumping to them
14 #include "vim.h"
17 * This file contains routines to maintain and manipulate marks.
21 * If a named file mark's lnum is non-zero, it is valid.
22 * If a named file mark's fnum is non-zero, it is for an existing buffer,
23 * otherwise it is from .viminfo and namedfm[n].fname is the file name.
24 * There are marks 'A - 'Z (set by user) and '0 to '9 (set when writing
25 * viminfo).
