Hi

I was able to get the whole column value from the single row but still for a single column it seems to do wonders. Any idea reagarding it.

my @array=(    [0,1,2,3,4],
            [25,26,27,28,29],
            [10,11,12,13,14]
            );
print @{@array[0]}[0..4];

This prints 01234 as required.

But
my @array=(    [0,1,2,3,4],
            [25,26,27,28,29],
            [10,11,12,13,14]
            );
print @{@array[0..2]}[3]

This prints 13... The logic is ok but the way arrays are constructed in perl marks this limitation.

Update: I hope this is a limitation in perl. The basic datastructure that is used to store the arrays store the start locatation of the array. In case of multidimentional arrays its the array of arrays so it is stored as a reference to the reference where it points out to the row. Hence we can retrive the row in above mentioned method but not the vice versa.
So it not possible to get the 0..23 from the array without the use of for loop or any other extra logic
