   I'd rather eat dirt.  I've been eliminating stuff like:
      system(strcat(strcpy(s, "set prot=(o:rwed) "), d));
(when it's pointed out to me) and I'd prefer not to add more. 
(The $QIO code to replace that irritant was impressively
longer and more complex, but far more satisfying.)  Error
messages, among other things, are easier to control when
using real system services.

   But I could make some sense out of the $QIO docs, which I
can't say about the $SET_DEVICE docs.
