You can make changes to script programs based on language.
Suppose, you are having a script program in language D, now if want to make changes to script program in language E. You can copy the script(lang D) to lang E and make the changes to the script you want to.
Open the script(lang D) in Change mode, Layout Set -> Copy from -> specify lang E -> Ok.
Now, you will be having two scripts, one in language E and other in language D.
