Hi Ppeoc,

I see what you mean. If it's always the first row, it's fairly simple: print join(",", @{$a1[0]}, @{$a2[0]}), "\n"; - for an explanation of the dereferencing syntax see perlreftut and maybe perldsc. If you want to do this to all the rows, assuming both arrays have the same number of rows, just add a loop:

my @a1 = (
    ['a','b','c'],
    ['d','e','f'],
    ['g','h','i'] );
my @a2 = (
    ['j','k','l'],
    ['m','n','o','p'],
    ['q','r'] );

for my $r (0..$#a1) {
    print join(",", @{$a1[$r]}, @{$a2[$r]}), "\n";
}

__END__

a,b,c,j,k,l
d,e,f,m,n,o,p
g,h,i,q,r

And if you want single quotes around the values: print join(",", map {"'$_'"} @{$a1[0]}, @{$a2[0]}), "\n";

Hope this helps,
