If you are using the PC version of SAS 9.4 and have set up automatic saving as described below, then the program you are editing may remain in the folder %AppData%\SAS\EnhancedEditor.
Please note, however, that the program remains in case SAS is terminated unintentionally, and not if SAS is terminated normally.

Saving before running is always a good idea.
