Purpose |
Determine whether a keyboard or mouse event is ready to be retrieved from the console input buffer. |
|
Syntax |
x = INSTAT |
|
Remarks |
The x variable receives the keyboard buffer status. INSTAT return logical TRUE (non-zero) if a keyboard or mouse event is ready to be retrieved from the console input buffer, or FALSE (zero) if there are no events in the buffer. INSTAT does not remove a keyboard or mouse event from the buffer. So if INSTAT ever returns TRUE, it will always return TRUE until the event is removed from the buffer using INKEY$ or WAITKEY$. Mouse support must be enabled in order to test for mouse events. INSTAT is not subject to redirection. |
