| For particular events within the mAirList programme, i. e. when a player is started or some marker is passed whilst playback, mAirList is calling an associated procedure by default. If no background script is available, no further action is taken.

| The code can simply be typed into a text editor. Windows-supplied ''notepad.exe'' does the trick flawlessly, however, for major projects the use of some dedicated code editor, like [[https://notepad-plus-plus.org|Notepad++]], might be considered. The finished code is to be saved in UTF-8 format into a file **with the extension ''.mls''**. | The code can simply be typed into a text editor.

| It is highly recommended to structure the code by indenting the statements with two whitespaces at a time.
