DOS maintains a table of values called environment variables. values in the environment table typically store information abut such things as the current drive and path, the location of the command processor, or special settings needed y various programs.
The Environ and Environ$ functions allow the program to read the current setting of the operating system's environment table . Entries in the environment table are set by using the DOS command syntax SET ENTRY_NAME = ENTRY_VALUE. see a DOS reference manual for more information on the SET command. Environ allows you to specify either the name or position of the entry to be retrieved.
