Editing List of DOS commands (section)

=== SET ===
Sets [[environment variable]]s.

The command is available in MS-DOS versions 2 and later.<ref name="RUNNINGMSDOS" />

[[cmd.exe]] in Windows NT 2000, 4DOS, 4OS2, 4NT, and a number of third-party solutions allow direct entry of environment variables from the command prompt. From at least Windows 2000, the <code>set</code> command allows for the evaluation of strings into variables, thus providing ''inter alia'' a means of performing integer arithmetic.<ref>{{cite book
