You can do it like 
open (IN,"| hellop.pl $my_value") or ...... ;
my @retvals = <IN> ; # or do it with a while(<IN>){}
close IN ;

[download]
hello.pl can access the value via $ARGV[0]

But be careful with processing user input! For example, what if $my_value contains '10 | rm -rf /' ( maybe the '|' should be a ';', I don't know, but I'm not a hacker)
Than you can as well do @retvals = `hello.pl $my_value`

I think you see the poin!
