It is a simple data base consisting of first elements all 10 diget numbers followed by anouther three elements in each line. I open my data base and extract the contents thus. 
"$data_file="learn.data";
open(DAT, $data_file) || die("Could not open file!");
@raw_data=<DAT>;

This gives me the contents of my database as an array. I also have a ten digit number, I now need to search the array and ask if this number is in the array. If so give me the other elements in that line. Simple for some hard for me...Please help.

update (broquaint): title change (was simple for some)
