How to enable the enter key so that MapBasic commands are executed from the MapBasic Window in MapInfo Pro when pressing enter?

Products affected: MapInfo Pro™
In MapInfo Pro v16.0 64-bit there is an option to disable the Enter key from executing code when it is pressed from the MapBasic Window.

Go to PRO > Options > MapBasic > double check the setting for "Enter Key executes command" (If unchecked then the Enter key is disabled, if checked, then it is enabled)
