According to the man page you are right. The man page of "system" refers 
to "5 wait" regarding the exitstatus which mentions that you should use 
the macro "WEXITSTATUS(status)" to get the exitcode which will return 
(according to its implementation) return the upper 8 bits of the status 
(which is a 16 bit value).
