Hello Friends!
I have been trying to print out a HoA. When I do so using the typical method of: 
 for $zz(keys %data) {
    print OUTPUT "@{ $data{$zz} }" 
}

I get all of the arrays printed out succesively. Each array is composed of several thousand data strings followed by a \n. From an Excel perspective, it would be the equivalent of 4 columns of several thousand rows (per array). What I am aiming to do is get these arrays printed out in succesive columns, so (again in Excel terms) it would be a total of 4 columns x 5 arrays =20 columns total. Anyway, I know that the best way to do this is to say  print "@a,@b,@c";so that they are all printed simultaniously. Hence, I have fished the keys of the array out (the name of the arrays themselves) using  my $scalar= join( ', ',keys %data); Therin lies my problem however. I have the names of the arrays in a scalar, but like calling a program in a different subdirectory, need to be able to pull out the names and figure out how to print the arrays themselves, rather than the names of the arrays. I hope I have elucidated my goals well. Thanks so much!!!
