You can use the redirection operator on the AIX Operating System command line to redirect input to and output from your XL Fortran program. How you specify and use this operator depends on which AIX shell you are running. Here is a ksh example:
$ cat redirect.f
write (6,*) 'This goes to standard output'
write (0,*) 'This goes to standard error'
read (5,*) i
print *,i
end
$ xlf95 redirect.f
** _main === End of Compilation 1 ===
1501-510 Compilation successful for file redirect.f.
$ # No redirection, input comes from the terminal, output goes to
$ # the screen.
$ a.out
This goes to standard output
This goes to standard error
4

$ # Create an input file.
$ echo >stdin 2
$ # Redirect each standard I/O stream.
$ a.out >stdout 2>stderr <stdin
$ cat stdout
This goes to standard output
2
$ cat stderr
This goes to standard error
