It's probably because you are using to_date on a date. Sysdate is a date, I imagine dob is as well. Doing so is a bug.
to_date does not accept a date parameter. So oracle implicitly converts the date to a varchar using your sessions date format.
i.e.
is really
to_date(to_char(sysdate, <nls_date_format>), nls_date_format)
Try getting rid of the to_dates.

Yes now it is giving correct output.
I thought that before to_date()-to_date() only can give the output.
Oh ...it has really gave me some bugs only.
This is the one lead to me the correct way.
SELECT to_date(TO_CHAR(sysdate,'DD/MM/YYYY'),'DD/MM/YYYY')-
to_date(TO_CHAR(dob,'DD/MM/YYYY'),'DD/MM/YYYY')
INTO v_sub
FROM customer_details
WHERE application_id=p_id;
v_dobcalc :=ROUND(v_sub/366);
But what is that -73 indicate? is it a ASCII value which we get as a result of the subtraction.
Thank u.

Out of topic: your solution just reminded me this comic (although you have still some place to improve): http://xkcd.com/763/

As the value is probably supposed to be date difference in years (by the way incorrect - although year 2012 has 366 days, most other ones do not) and 27-(-73)=100, this is just a side effect of having two digit year (most probably 'YY') in NLS_DATE_FORMAT mask. So, DOB is converted to e.g. string DD-MM-85, which is supposed to be in year 2085 and not 1985. Anyway, when you avoid implicit conversion, NLS_DATE_FORMAT will not be used and it will be processed correctly.
To the difference count: subtraction gives the difference in days; for getting years, use MONTHS_BETWEEN function and divide it by 12 (fortunately, all years have 12 months).

I tell you that using to_Date on a date is a bug. I explain that it's a bug because to_date doesn't accept a date parameter and oracle has to implicitly to_char it first.
I then explicitly tell you to remove the to_date.
You instead add the implicit to_char explicitly.
You really didn't read my post very carefully did you?
Don't change datatypes if you don't need to.

The difference in the counts will have been due to different nls_date_formats being used by sqlplus and forms. Forms will have been using YY and sqlplus YYYY.
I agree that months_between is the best way to do this.
