In fact this is not really what you want in VMS, since /input etc will cause
the program to be run in a subprocess, whereas ordinarily programs are all
run in the same process.  So the real VMS syntax is:

$ define/user sys$input source
$ define/user sys$output destination
$ define/user sys$error error-log
$ run myprog

which I think is sufficiently gross to discourage people from using
redirection as the main technique to specify files for programs to use.
