The three Csound environment variables SFDIR, SSDIR
and SADIR can be edited in the environment window.
The settings in this window are global and will be passed to every Csound
job during
execution.
Environment variables can be saved in a file, just like ordinary jobs. However, because the environment is global and used by all the jobs in the Csound Shell, opening an environment file will not cause a new job window to open; instead, the values read from the file simply replace the current global settings.
The Csound program uses the values of the environment variables when searching for files; see the Csound manual for details.
