Purpose |
Determine whether a keyboard character is ready. |
|
Syntax |
GRAPHIC INSTAT TO numeric_variable |
|
Remarks |
The numeric variable receives the keyboard buffer status for the selected graphic target. The value assigned is TRUE (non-zero) if a keyboard character is ready to be retrieved, or FALSE (zero) if not. GRAPHIC INSTAT does not remove the character from the buffer, so repeated execution will continue to return TRUE until the character is read with GRAPHIC INKEY$, GRAPHIC INPUT, etc. |
