Command Prompt for Windows




Command XSET

Function:

Display, set or remove persistent environment variables.

Syntax:

XSET [variable=[chars]]
variablePersistent environment variable name.
charsA series of characters to assign to the variable.

Note:

The persistent environment variables are stored in the system registry and Windows NT will automatically include these environment variables in the environment space for all programs. Also, setting or deleting a persistent environment variable will cause all interested programs to update their environment space immediately (eg. Program Manager, the WinOne® Command Prompt etc).

Type XSET with no parameters to display a list of all the persistent environment variables.

When parameter chars is not specified then the persistent environment variable will be removed from the environment space,

The PATH environment variable is a special case and is made up of 3 parts, as below :-

system_path ; persistent_path ; autoexec_path

Command XSET will only manipulate the persistent_path part of the complete PATH environment variable. For example, to add C:\TEST enter at the command prompt :-

XSET path=c:\test

and the resulting PATH environment variable will be :-

system_path ; c:\test ; autoexec_path

Command XSET is not available under Windows 95.

Example on using XSET.
