   ...The return value is the exit status of the program
   as returned by the "wait" call.  To get the actual
   exit value divide by 256.

So he *is* testing the rsh exit status (at least 0 vs non-zero). 
The problem is that rsh does not return the exit status of the 
command it is running, which is what the OP is trying to check. 
$? will not help him with that.

You are testing the exit status of the system call, not the exit status of
the rsh call which is in $?.
You need

$systemstatus=system(...);
$rshstatus=$?;

The exit status of rsh is 0 if it was able to connect to the remote
system. It doesn't return the exit status of the command being run.

Try

$result = `rsh $plant /u1/bin/forkit '/u1/bin/work.pl'`;

print $result;

You are storing the output of the rsh... command into the variable. You can
now run a regex on that to check for success/failure.

I don't know what the output should be but as an example...

$result = `rsh $plant /u1/bin/forkit '/u1/bin/work.pl'`;

if ($result =~ /worked/i) {
print "Yep, that worked\n";
} else {
print "Ooops. Something went wrong: $result";
}

I took out the exec and placed system.  But even though work.pl doesn't 
exist on the remote system, still getting no error.  Help!

if (system("rsh $plant /u1/bin/forkit '/u1/bin/work.pl'") > 0)
  {
excep(" $!\n");
  }
