Enables programs to open data files in specified directories as if the files were in the current directory.Do not use this command when Windows is running.
The specified directories are called appended directories because, for the sake of opening data files, they can be found as if they were appended to the current directory.
APPEND [drive:][path[;...]] [/X | /X[:ON | :OFF]] [/PATH[:ON | :OFF]] [/E]
To clear the appended directory list:
To display the list of appended directories:
Caution Do not use APPEND with Microsoft Windows or the Windows Setup program.
PATH - To set a search path for executable files.
Do not use APPEND with Microsoft Windows or the Windows Setup program.
You can use APPEND as many times as you want after starting your system. However:
You can use the /E switch with APPEND to assign the list of appended directories to an environment variable named APPEND. To do this, first use the APPEND command with only the /E switch. Then use APPEND again, this time including the directories you want to append. You cannot specify /E and [drive:]path on the same command-line.
To append more than one directory, separate multiple entries with semicolons. If you use the APPEND command with the [drive:]path parameters again, the specified directory or directories replace any directories specified in a previous APPEND command.
If you specify the DIR command, the resulting list does not include filenames from appended directories.
If a file in an appended directory has the same name as a file in the current directory, programs open the file in the current directory.
When a program opens a file in an appended directory, the file can be found as if it were in the current directory. If the program then saves the file by creating a new file with the same name, the new file is created in the current directory (not the appended directory). APPEND is appropriately used for data files that are not to be modified or that are to be modified without creating new copies of the files. Database programs often modify data files without making new copies. Text editors and word processors, however, usually save modified data files by making new copies. To avoid confusion, do not use APPEND with these programs.
When /X:ON is specified, you can run a program located in an appended directory by typing the program name at the command prompt. Usually, you use the PATH command to specify directories that contain programs. However, when your program is in an appended directory, you do not need to use the PATH command to specify that directory. A program in found in an appended directory by following the usual order in which is searched for a program; that is, first in the current directory, then in the appended directories, and then in the search path.
Even when the /X:ON switch is not specified, appended directories are used when programs call operating system Interrupt 21h functions:
When /X:ON is specified, appended directories are used when programs call any of the Interrupt 21h functions in the preceding list or any of the Interrupt 21h functions:
You can use the APPEND command to append directories that are located on network drives.
To allow programs to open data files in a directory named LETTERS on the disk in drive B and in a directory named REPORTS on the disk in drive A as if the files were in the current directory, type:
To append the same directories and keep a copy of the list of appended directories in the environment, type:
APPEND /E APPEND B:\LETTERS;A:\REPORTS
These must be the first APPEND commands you use after starting your system.
