Hi birei,

Thanks a lot for your reply.

After using the "Split" function and then while saving the columns into an array,
I am struggling how to eliminate the first 231 lines and the last 4 lines, because these are the header information and footer information.

Code:
@array = <F>;
close F

my @fields;

foreach (@array) {

$line = $_;
@fields = split (/\|/, $line);

print OUT join( "\t", @fields[1, 3 .. 7, 10 ..13, 15 .. 33, 36, 37, 40, 55 .. 66, 68 .. 103, 104, 105 .. 107, 109 .. 128, 130 .. 137, 187] ), "\n";
}
close OUT;

how do I use the array splice while saving the column values into the array ?

Code:
@array[231..$#array-4];

Could someone please help me out to eliminate the Header and footer information while saving the data into the array ?

Would really appreciate your thoughts.
