* Calling the statement with no parameters enables all four possible full screen modes (and is the default state when a program is started): both [[_STRETCH]] ([[_SMOOTH]] and [[_OFF]]) and [[_SQUAREPIXELS]] ([[_SMOOTH]] and [[_OFF]]).
** Using [[_ALLOWFULLSCREEN]] [[_ALL]], [[_ALL]] has the same effect.
* [[_ALLOWFULLSCREEN]] only affects the behavior of ALT+ENTER. The [[_FULLSCREEN]] statement is not bound by [[_ALLOWFULLSCREEN]]'s settings so all modes can be accessed programmatically.
* To limit just the mode but allow both _SMOOTH + _OFF antialiasing modes, pass just the first parameter: ''Example:'' [[_ALLOWFULLSCREEN]] _SQUAREPIXELS
* To allow multiple modes with _SMOOTH or _OFF as default, pass just the second parameter. ''Example:'' [[_ALLOWFULLSCREEN]] , _SMOOTH
* Any possible permutation of the parameters is allowed.
* With [[_ALLOWFULLSCREEN]] _OFF you can trap Alt+Enter manually in your program and reassign it. See example 2 below.
