Sorry to butt in here with a novice question but this issue is
something I've recently been trying to use in some scripting.
I thought this might be one way to get at the exit status of system,
maybe its not such a good way?
if((system( "$somecmd $cmdflgs"))== 0){
print "Yippie <$somecmd $cmdflgs> completed successfully\n";
}
