CALL System(Command, Status)
Command: CHARACTER; scalar; INTENT(IN).
Status: INTEGER(KIND=1); OPTIONAL; scalar; INTENT(OUT).
Intrinsic groups: unix.
Description:
Passes the command Command to a shell (see system(3)).
If argument Status is present, it contains the value returned by
system(3), presumably 0 if the shell command succeeded.
Note that which shell is used to invoke the command is system-dependent
and environment-dependent.
Some non-GNU implementations of Fortran provide this intrinsic as only a function, not as a subroutine, or do not support the (optional) Status argument.
