give subscript as 11 ,like if we have temp as table name, 
then
display "temperature : " temp(11)

but if table is two dimentional then
__________________________
|     1     |    2       |
|_________ _|____________|
|     |     |     |      |
|0-25 |26-50|51-75|76-100|
|_ele_|_ele |_ele |_ele  |

so to fetch 11 the record we have to write temp(1,11)

index
   0 1 2 3 4 5 6 7 8 9
0  |
1-this is 11 th item in array
2
3
4
5
6
7
8
9 
that is arrymame(1,0)=11th item

i think above answers r worng.
