The return value of the system call will be whatever the sample.pl exits
with. If the sample.pl encounters an error while processing and calls exit
with a value other then 0, then that value will be saved in $retval
(assuming your example code).

Yes. It is fine. This will continue the processing as soon as the sample.pl
exits which seems to be exactly what you want it to do.
