Hello Gr8 11

I open a pipe from one Perl program to another like so

open (PROG, "|$HOME/server/bin/prog.pl")||die "Cannot open $HOME/server/bin/prog.pl"

And then I print anywhere from 1 million to 2.5 million lines of data like so 

 
foreach $line (@array){
   print PROG "$line\n";
}

[download]

But I just made some modifications to prog.pl which necessitates passing data back to the calling script. What can I do (Can I read from the pipe, or is there another way I can get data passed back)?

Thank you so much!
