If you are ill and visit a doctor: do you tell him your exact symptoms or just "it hurts"?
Show us what you did, what your input was, what your output was and how it differed from the expected output. Otherwise this is going to be a trade of "it works", "no, it doesn't", "yes, it does", "no, it doesn't", ... ad libitum ad nauseam.
Please take note: if you can't be bothered to tell us exactly what you want and how our suggestions fail (in other words: invest effort into your question) we won't be bothered to invest any effort in answering these question of yours. This here is give and take - and right now you are taking without giving.

To match range, the command is:
awk '/BEGIN/,/END/'
but what I want is the range is printed only if there is additional pattern that matches in the range itself? maybe like this:

arithmetic
ARITHMETIC(6) BSD Games Manual ARITHMETIC(6)
NAME
arithmetic -- quiz on simple arithmetic
SYNOPSIS
arithmetic [-o +-x/] [-r range]
DESCRIPTION
arithmetic asks you to solve problems in simple arithmetic. Each question must be answered correctly before going on to the next. After
every 20 problems, it prints the score so far and the time taken. You can quit at any time by typing the interrupt or end-of-file character.
The options are as follows:
-o By default, arithmetic asks questions on addition of numbers from 0 to 10, and corresponding subtraction. By supplying one or more
of the characters +-x/, you can ask for problems in addition, subtraction, multiplication, and division, respectively. If you give
one of these characters more than once, that kind of problem will be asked correspondingly more often.
-r If a range is supplied, arithmetic selects the numbers in its problems in the following way. For addition and multiplication, the
numbers to be added or multiplied are between 0 and range, inclusive. For subtraction and division, both the required result and the
number to divide by or subtract will be between 0 and range. (Of course, arithmetic will not ask you to divide by 0.) The default
range is 10.
When you get a problem wrong, arithmetic will remember the numbers involved, and will tend to select those numbers more often than others, in
problems of the same sort. Eventually it will forgive and forget.
arithmetic cannot be persuaded to tell you the right answer. You must work it out for yourself.
DIAGNOSTICS
``What?'' if you get a question wrong. ``Right!'' if you get it right. ``Please type a number.'' if arithmetic doesn't understand what you
typed.
