Hi Perlmonks.. Is it possible to map not just one array before the grep function?? In this case I want to print the elements in the array which contains the word 'EMBL' : 
print OUT join "\n", map {${$_}[1]}grep { ${$_}[0] eq "EMBL" } $entry-
+>DRs->elements;

In this case what if I want to map ${$_}[1] and ${$_}[2] both at the same time?? I try using 
print OUT join "\n", map {${$_}[1],${$_}[2]}grep { ${$_}[0] eq "EMBL" 
+} $entry->DRs->elements;

But either comma or colon, they still give me some error. And what if I want to map all the elements in the array?? I have tried without the map function such as 
print OUT join "\n",grep { ${$_}[0] eq "EMBL" } $entry->DRs->elements;

But it doesn't print the content of the array but only the address : ARRAY(...). Thank you in advanced.
