Working with Files
Open a file
Before you can do anything with the project or the script,
the file must be open.
Save a file
Not to lose the changes, the user should save projects and scripts in time.
Run a project or a script
Once the project or the script is ready, it can be run.
Kill a project or script
The project or script execution can be killed by
double-clicking its name in the list of running processes.
Close a file
Finally, when the file is not edited or executed any more, it
can be closed.
