The main reason to do it this way is that when a startup script contains "set nocp" the following lines often depend on this. If one would start "vim -C" and the -C would cause the "set nocp" line to be ignored, the rest of the script would be misinterpreted. Especially for ":map" commands with things like "<C-A>". With 'nocompatible' this means CTRL-A, with 'compatible' this is 5 separate characters. One could think of having the "set nocp" only apply to that script and restore the 'compatible' option value after it has been sourced, but that is a bit complicated. - Bram -- A)bort, R)etry, B)ang it with a large hammer /// Bram Moolenaar -- [EMAIL PROTECTED] -- 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 /// -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
