This option creates a new window in which you can write your program.
The focus is set to the new window. Depending on the environment settings, the window is normal sized or maximized.
Note that you must save your program before you can compile it. Newly created files will have the name [nonameX] in the window caption. Where X is a number starting with 1 for the first editor window.
Before you can compile your program, you must give it a valid name.
