恢复已经删除程序

I recently deleted a custom program (which is already transported to production) accidentally and was wondering if there is any method of retrieving the program back. After some research, I found a way of getting back the program. Following are the steps in getting back the program:

1) Create a program with the same name as earlier (which is deleted) 
2) Click on "Utilities" --> "Versions" --> "Version Management" 
3) Select the version of your earlier program and click on display. 
4) Your earlier program is displayed here.
