DOS Set

An internal command that sets environment variables, which are stored values used by DOS as well as many applications. PATH, APPEND, COMSPEC and PROMPT are actually environment variables too.

An environment variable is often used to indicate where temporary files are stored, such as in the following example:

               set temp=c:\dos

To display the current values for all the environment variables, type:

                     set

Important!
In other DOS commands, spaces after the equals sign don't matter. With Set, they do. The command set state = IL would make the first character of the STATE variable a blank (" IL").
