Re: [7stud] problem in error handling.

Can system() cause an error?
Since system is a built-in function, if it "causes" an error, then your Perl installation is corrupt.

The adjustment I made compares the return code of the system call to 0 and if they are not equal, then the command being executed failed, not Perl's system function.

See `perldoc -f system`
