how to set environment variables for msdos using the path append and tree command

In this video we discuss how to set environment variables for msdos using the path append and tree command

Time Codes:
dos path command 0:48
dos append command 2:10
dos tree command 3:49

the path environment variable is a list of directories where ms dos will check for a file. the path command in dos allows you set the path variable

Path is used to specify the location where MS-DOS looks when using a command. For example, when using the command "format," if the path is not specified to where the command is you will receive bad command or file name.

The path command is an internal command that is available in all versions of ms dos

Displays or sets a search path for executable files.

PATH [[drive:]path[;...]]
PATH ;


Similar to path in dos , the append command in dos enables a user to open files in the specified directory as if they were in the current directory which is one of the dos environment variables

The dos append command is an external command available in ms dos versions 3.2 and above

Append syntax
APPEND Drive: \Path /X /E Path:on or off

Drive: The drive letter to be searched.
\Path The path to be searched.
/X :on or :off Extends the DOS search path for specified files when executing programs. Processes SEARCH FIRST, FIND FIRST, and EXEC functions. The :ON and :OFF are new to version MS-DOS 5.0.
/Path :on or :off If path is already included for a program file, :on tells program to also search in appended directories. Default= :on. Note: The default value of = :on was added in MS-DOS 5.0 and above.
/E Causes the appended path to be stored in the DOS environment and searched for there.
; Use ";" to separate multiple Drive:\path statements on one line.

The tree command is an external command that is available in all version of ms dos

Tree syntax
TREE [Drive:[[Path] [/F] [/A]

Drive:\Path Drive and directory containing disk for display of directory structure.
/F Displays file names in each directory.
/A ext characters used for linking lines, instead of graphic characters. /a is used with code pages that do not support graphic characters and to send output to printers that do not properly interpret graphic characters.
