examinekeyboard needs open(window)screen ?

[sartic]

If Not(InitKeyboard())
End 99
EndIf
If ExamineKeyboard()
If KeyboardReleased(#PB_Key_Pause) Or KeyboardReleased(#PB_Key_Scroll)
Break
EndIf
EndIf

there is no explanation in help.
strange thing it works compiled on my system but it gives error on run.

ps: in help file there is no result for examinekeyboard so there is no need for if in this program?

The keyboard library docs do say it depends on DirectX but they should really go on to say a screen needs to be open as well, that seems to be a deficiency in the help file.

Isn't reported by the debugger ?

"OpenScreen() or OpenWindowedScreen() must be called before using any Keyboard commands."

Anyway a mention in the manual wouldn't hurt.

yes, it is. but works on my system, crashing on other without openscreen (it depends on initsprite etc...)
i will investigate how to check for key input without dx.
