You are asking for miles:
T True means output distance values in miles

Yes, and east longitudes! If you want Auckland, NZ, it could be:
-36.9000 -174.8000 45. BigAl's Home
>>(3) For prediction date of 01/10/97 (dd/mm/yy) why does the prediciton
heading say that I have generated a prediciton for the evening of 02/10/97
and morning of 03/10/97? I thought if I put in a date of 01/10/97 it would
predict for evening of 01/10/97 and morning of 02/10/97? (poss something to
do with the +12 time zone?)

Yes, if you set -12 you should be better off. I think QuickSat starts
at noon UT, when it is already 00:00 on the day after for you.
The documentation says it starts with the evening, and following morning,
and that appears to be before applying the TZ correction.
If you really are in Auckland, you won't get an evening pass, and no
morning pass until Oct.7 :
1997 10 Year, month number
1 7 Start date, end date
-0.3 0.5 Start time, end time, "A" flag
-36.9000 -174.8000 45. BigAl's Home
-12 CDT 12 correction for UT to time zone, time zone name, 12/24 flag
