At the character just after the end of the line it returns the syntax state at that position. It's always a bit tricky if this is just before, at or after the line break. Note getting back a List means the arguments are wrong. This also happens if the line number is out of range. I don't think making an exception for when the column number is out of range is useful. -- Experience is what you get when you don't get what you want. /// Bram Moolenaar -- b...@moolenaar.net -- http://www.Moolenaar.net \\\ /// sponsor Vim, vote for features -- http://www.Vim.org/sponsor/ \\\ \\\ download, build and distribute -- http://www.A-A-P.org /// \\\ help me help AIDS victims -- http://ICCF-Holland.org /// -- You received this message from the "vim_use" maillist.
