- * Keyboard_Events.c
- *
- * This example does not work very well in a system where
- * input.device is active since input.device also actively calls for
- * keyboard events via this call. For that reason, you will not get all of
- * the keyboard events. Neither will the input device; no one will be happy.
- *
- * Compile with SAS 5.10 lc -b1 -cfistq -v -y -L
- *
- * Run from CLI only
