os_msdos.txt For Vim version 9.0. Last change: 2016 Feb 26 VIM REFERENCE MANUAL by Bram Moolenaar msdos ms-dos MSDOS MS-DOS This file used to contain the particularities for the MS-DOS version of Vim. MS-DOS support was removed in patch 7.4.1399. If you want to use it you will need to get a version older than that. Note that the MS-DOS version doesn't work, there is not enough memory. The DOS32 version (using DJGPP) might still work on older systems.
