Your DOS environment, which stores a number of important items,
including the location of COMMAND.COM (COMSPEC), your PATH
(PATH), your PROMPT string (PROMPT) and variables to control
programs and batch files. Using the DOS SET command, you can
alter anything in your path, but it's inconvenient.
EnvEd can change any or all of your DOS environmental variables.
Just type ENVED and press ENTER to see all of the environment displayed
on a word-processorlike screen. Instead of retyping the entire
command, you can use EnVed like a word processor to alter the
environment however you like.
EnvEd will run on any IBM-compatible PC with a minimum of 128K of
memory. It requires DOS 2.1 or a later version, and will run on
monochrome or color systems.
It's best to install the ENVED.EXE file in a directory named in
your PATH statement. That way, you'll be able to run the program
regardless of your current directory. For more information on
the PATH statement, see your DOS manual.
Once installed, you start the program with this command:
You'll see a full screen showing the current state of your
environment. Use the normal cursor keys to move around on the
screen. EnvEd is normally in Insert mode, so characters you type
push all characters after the cursor to the right. To switch to
overtype mode, just press Ins. The Ins key is a toggle that
switches you back and forth between insert and overtype modes.
After making any changes you want, you can save your new
environment and exit to DOS by pressing Ctrl-K, X. It's just like
the WordStar command. To exit without saving your changes, just
Your DOS environment is limited in size, and EnvEd knows just how
much you can enter. If you try to exceed the available
environment space, EnvEd simply won't accept the characters. A
running display of environment space, in bytes and percent used,
appears at the top of the screen. You can increase your
environment space, but methods vary according to DOS version.
Consult your DOS manual for more information.
Limited help is available by pressing F1.
EnvEd does no checking on the validity of your entries. See your
DOS manual for the correct formats for all environment variables.
Use caution when altering the COMSPEC variable. If you make an
error, you may have to reboot after exiting EnvEd.
If you run EnvEd while temporarily shelled out to DOS from another
program, the changes you make may not remain after you return to
the program, or when you exit to DOS. Environment changes are
only retained if you make them from your main DOS prompt.
EnvEd is written in Turbo Pascal 5.0, with some routines by
