`OPEN', `CLOSE', and `INQUIRE' Keywords
---------------------------------------

   `g77' doesn't have support for keywords such as `DISP='DELETE'' in
the `OPEN', `CLOSE', and `INQUIRE' statements.  These extensions are
easy to add to `g77' itself, but require much more work on `libg2c'.

   `g77' doesn't support `FORM='PRINT'' or an equivalent to translate
the traditional `carriage control' characters in column 1 of output to
use backspaces, carriage returns and the like.  However programs exist
to translate them in output files (or standard output).  These are
typically called either `fpr' or `asa'.  You can get a version of `asa'
from `ftp://sunsite.unc.edu/pub/Linux/devel/lang/fortran' for GNU
systems which will probably build easily on other systems.
Alternatively, `fpr' is in BSD distributions in various archive sites.
