When I look in the help files for vl-file-systime, it shows the return as: The list returned contains the following elements: year month day of week day of month hours minutes seconds But when I use vl-file-systime it returns another number at the end of the list. Can anyone tell what this is? Command: (vl-file-systime "g:/lsptemp/pline.dwg") (2004 6 3 2 6 5 12 976) Command: (vl-file-systime "g:/lsptemp/pb.lsp") (2004 5 1 24 10 0 26 835) TIA Bill
