Extensions are identified with the @ prefix.

There are three types of usage: get, set and call.

Not all extensions allow all the same usage.

  • Get: For get the result of it, expand it:
echo %@theextension%
  • Set: For set a value as parameter to the extension:
set "@theextension=value"

Note: In the set, when the values are booly, the next values are equivalent:

0, no, off, false

1, yes, on, true

  • Call: For call the extension like an internal command:
call @theextension parameter
