 Here is an example setting the cursor in the middle of the screen:
 
 ```c
+digitizer_t digitizer;
 digitizer.x = 0.5;
 digitizer.y = 0.5;
 digitizer.tipswitch = 0;
 digitizer.inrange = 1;
-digitizer.status |= DZ_UPDATED;
+digitizer_set_report(digitizer);
 ```
 
-The `tipswitch` member triggers what equates to a click when set to `1`. The `inrange` member is required for the change in coordinates to be taken. It can then be set to `0` in a new report to signal the end of the digitizer interaction.
+The `tipswitch` member triggers what equates to a click when set to `1`. The `inrange` member is required for the change in coordinates to be taken. It can then be set to `0` in a new report to signal the end of the digitizer interaction, but it is not strictly required.
 
 Once all members are set to the desired value, the `status` member needs its bitmask `DZ_UPDATED` to be set so the report is sent during the next main loop iteration.
