This page displays information abot the environment space.
The environment space is used to hold information for programs to use. It
is controlled by using the DOS command SET.
Some commonly used variables:
COMSPEC: This is the program that controls the DOS prompt. It is also used
when you 'Shell to DOS' from programs.
PATH: These are the directories DOS will search when you type a command
it doesn't internally know. It first searches the current
directory, then all of the ones listed on the PATH. It tries each
directory by looking for a file with a .COM, .EXE, or .BAT
extention, in that order.
PROMPT: This is used to display the prompt.
TEMP: Used by many programs and DOS 5. Should point to a directory or,
more commonly, a RAMDISK, and is used by programs for temporary
storage.
Many programs use environment variables to hold information, such as
where their startup files are, and startup commands. INFOPLUS supports an
environment variable. If used, it contains the directory where INFOPLUS's
INFOPLUS.HLP file is located. If the .HLP file is in the same directory as
INFOPLUS.EXE, then you don't really need the environment variable.
