Hi

As far as I am aware it means the variable type, in this case an integer value between -32768 and +32767.

Regards

Hi Ian
The Z (Z meaning integer as chipfryer27 correctly said) without a + sign is an signed integer, with a range is from -32768 to 32767
The + just means you can't have a negative number, only 0 or positive.
If the Z has a + then it's a unsigned integer, with a range is from 0 to 65535
The notation Z for integer comes from the German word Zahlen, which means "numbers".
So as the Z in your case is a signed you can only have a range from -32768 to 32767.
