Hellow Monks.

I'm learning perl nowadays. It's very interesting.

But I have a problem. I can't solve....

please help me to solve this problem.

I want to merge two files.

but merged new file must have some format. and I want to know how I can do it.

and I don't want to solving problem by using modules, packages.

here's format

---------------------------------------------

file1 format

key key2 var0 var1 var2 data1

A A-0 a10 a11 a12 8

A A-1 a10 a11 a12 12

A A-2 a10 a11 a12 5

A A-3 a10 a11 a12 8

A A-4 a10 a11 a12 2

A A-5 a10 a11 a12 15

A A-6 a10 a11 a12 8

A A-7 a10 a11 a12 12

A A-8 a10 a11 a12 15

A A-9 a10 a11 a12 8

B B-0 a10 a11 a12 7

B B-1 a10 a11 a12 2

B B-2 a10 a11 a12 6

B B-3 a10 a11 a12 9

B B-4 a10 a11 a12 16

B B-5 a10 a11 a12 19

B B-6 a10 a11 a12 10

C C-0 a10 a11 a12 1

C C-1 a10 a11 a12 3

C C-2 a10 a11 a12 16

C C-3 a10 a11 a12 11

C C-4 a10 a11 a12 10

----------------------------------------------

file2 format

key var10 var11 data2

A b00 b01 6

A b00 b01 9

B b00 b01 10

C b00 b01 11

B b00 b01 9

A b00 b01 13

--------------------------------------------------

result file format ( file1 + file2)

key var10 key2 var0 var1 (data2-data1) key2 var0 var1 (data2-data1) key3 var0 var1 (data2-data1)

--------------------------------------------------

there are three key2 because I choose three lists in file1 that is most small in the range -5 <(data2-data1) < 5.

if there are two in the range than you can choose two. If there are four in the range then you can choose three that are most small number (data2-data1)

please. help me.
