use batch file to set global variables (1 Viewer)

[Guus2005]

How can i use a batch file to set a variable so that it doesn't vanish after the script is done?

rem File1.bat
set variable1=foo

rem File2.bat
echo %variable1%

When i run File2 after File1 variable1 is not recognised.

So the scope of variable1 is only within File1.bat present.
How can i change that?

Set it as an environment variable, or pass it on to next script.

it was mentioned here why it is Not Retained?
Set - Environment Variable - Windows CMD - SS64.com

this will work using .vbs (vb script):
VBS Read and Set Environment Variables – Geeks Hangout

//note; use the "user" instead of 'system'

The scope of variables in a batch file is restricted to that batch file.
@Gasman "Set it as an environment variable" how do i do that?

Yes. But nothing to stop you passing it on to the next batch file?
Use shell to execute the set command.
