Yes, sorry. I assumed since option '0' was 'help' that it wasn't simply an enumerated list. Obviously documented by a 'C' programmer. 
BTW, as far as I can tell, this function has been around in one form or another since 15.0 ESD#2
Would love to see many other fields added, like space management bits, number of deleted rows, forwarded rows, contiguous free space, etc.
