Aside from a couple of syntax errors, the code is "right" if it does what you want it to do. Here is a functionally equivalent re-write:

use strict;
use warnings;

my $generatorDir = './processing';
my @rprtname     = 1 .. 9;
for (@rprtname) {
    `perl $generatorDir/$_.pl`;
}

Your code will execute 9 scripts in sequence. If your code does not do what you want it to do, please explain how it differs from your expected behavior.

An enhancement would be to use system instead of backticks, and check the status of each command.

    system "perl $generatorDir/$_.pl" and die "Error running $_.pl $?"
+;

Updated above code to replace $! with $? (thanks AnomalousMonk).
