Je kunt ook een omgevingsvariabele maken die alleen voor een **specifieke programma-aanroep** beschikbaar is, die alleen voor dat programma beschikbaar is en alleen voor de duur van dat programma.

Om dat te doen, maak je het vlak voor het programma zelf aan, op dezelfde regel:

<div class="termy">

```console
