Obsolete Commands
This document describes some commands that are obsolete, etc.
FreeDOS does not support these commands.
append
Allows programs to open data files in the specified directories as though they were local to the
working directory.
[Dropped, because the program was considered to be a "crutch" for legacy DOS-based
applications as DOS moved to support directories. Append was used primarily to support
programs that did not know about directories on a DOS system.]
fastopen
Decreases the amount of time needed to load files and programs.
[Dropped, because disk cache should be (eventually) implemented in the kernel, not by an
external program. Also, Fastopen was originally created to increase DOS application
performance on systems with slow drives, where today disk drives are much faster.]
graftabl
Load the graphics table for a specific code page.
[Dropped, because most monitors can display extended characters (128-255) without
Graftabl. This command was originally introduced by MS-DOS to support the extended
character set on systems that were not originally equipped to display them properly. While
some users may miss this command, we feel there are not enough systems that still need
Graftabl to justify its inclusion in the Spec.]
recover
Recover data from a bad diskette or hard disk.
[Dropped, because there are a variety of shareware and freeware disk recovery programs
already avaialble, and it would be silly of us to write another one just because MS-DOS
included a Recover command. If you need a disk recovery program, go download one, or
purchase a third-party recovery program such as Norton's Utilities.]
setver
Set the DOS version that is reported to programs.
[Dropped, because this was a legacy migration thing, to allow programs that needed to run on a
particular DOS version to be carried forward.]
