Re: Environment variables in batch files?

From: "Linn Kubler" <lkubler@xxxxxxxxxxxxxxxxxx>

| Hi,
|
| Why is it that I can set an environment variable in a logon batch file but
| when I type 'Set' in a command window I don't see my environment variable in
| the list?

| Thanks in advance,

Because the variable is created and used in a daughter process and is not passed up to the
parent process. Once the batch file ends (or the Command Prompt closes) the daughter
process ends and the variable no longer exists.

In Win9x/ME Environmental Variables are added to the AUTOEXEC.BAT file and the system will
then need to be rebooted. Then the variables will be available (WinME actually will parse
the AUTOEXEC.BAT file and update the Registry) On NT based OS's you have to; Right click on
"My Computer", choose "Advanced", then "Environmental Variables" and add a "user" or
"global" (system) variable.. Then the variable will be available in all daughter processes.
