tasklist -v truncation of output - perl

Question

Evidently the Windows dos cmd "tasklist -v " is truncating lines after so many characters.
My perl program is reading in special command processes to compare against processes stored in my database. I am trying to make sure expected processes are running.
Unfortunately the script fails since one of my 50 or so processes is truncated by "tasklist -v".
Is there an alternative command?
Thanks,
Sammy

Following code demonstrates usage of tasklist /fo table command as a pipe input for further processing
Tip: help tasklist
use strict;
use warnings;
my $regex = qr/^(?<name>.*?)\s+(?<pid>\d+)\s+(?<session_name>\S+)\s+(?<session>\d+)\s+(?<mem>.*)/;
$^ = 'STDOUT_TOP';
open my $pipe, 'tasklist /fo table|';
/$regex/ && write for <$pipe>;
close $pipe;
$~ = 'STDOUT_BOTTOM';
write;
exit 0;
format STDOUT_TOP =
+----------------------------------+------------+----------+---------+-----------+
| Name | PID | SessName | Session | Memory |
+----------------------------------+------------+----------+---------+-----------+
.
format STDOUT =
| #<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< | #>>>>>>>>> | #<<<<<<< | #>>>>>> | #>>>>>>>> |
$+{name}, $+{pid}, $+{session_name}, $+{session}, $+{mem}
.
format STDOUT_BOTTOM =
+----------------------------------+------------+----------+---------+-----------+
.
