The '''$SCREENHIDE''' [[Metacommand]] can be used to hide the main program window throughout a program.


{{PageSyntax}}
::: $SCREENHIDE


* $SCREENHIDE may be used at the start of a program to hide the main program window when using a [[$CONSOLE|console]] window. 
* $SCREENHIDE must be used before the [[$SCREENSHOW]] [[Metacommand]] can be used!
* The [[_SCREENHIDE]] statement must be used before [[_SCREENSHOW]] can be used in sections of a program.
* '''QB64 [[Metacommand]]s require that commenting or [[REM]] NOT be used!'''
