{{PageSyntax}}
|
|
: [[$CONSOLE]][:ONLY]
|
|
|
|
|
|
* [[_CONSOLE]] '''ON''' or '''OFF''' may be used to show or hide the console window at run time.
|
|
* The ''':ONLY''' option can be used when only a console window is desired without a program window.
|
|
* [[_DEST]] [[_CONSOLE]] may be used to send screen output to the console window.
|
|
* [[_SCREENHIDE]] and [[_SCREENSHOW]] can be used to hide or show the main program window.
|
|
* [[_DELAY]] or [[SLEEP]] can be used to allow the console window to be set in front of the main program window.
|
|
* '''QB64 [[Metacommand]]s are not commented out with ' or REM, differently from Qbasic metacommands'''
|
|
* Change the title of the [[$CONSOLE]] windows created using [[_CONSOLETITLE]]
|
|
* '''Note:''' Text can be copied partially or totally from console screens in Windows by highlighting and using the title bar menu.
|
|
:: To copy console text output, right click the title bar and select ''Edit'' for ''Mark'' to highlight and repeat to ''Copy''
