INSTALL:
	  These instructions assume you have the following in /tmp  
		this README file (SC1.0.1_README), and
		a tar file of the directory SC1.0.1 (called SC1.0.1_tar)

	  Do either A or B:

	  A. If FORTRAN 1.4 was installed into /usr/lang
	     1. Put the files into /usr/lang:
	            cd  /usr/lang
	            tar  xvf  /tmp/SC1.0.1_tar
	     2. Remove the soft links of f77, as & fpversion to /usr/lang/SC1.0 
		    rm /usr/lang/f77
		    rm /usr/lang/as			(sun4 only)
		    rm /usr/lang/fpversion		(sun4 only)
	     3. Replace them with the soft links to /usr/lang/SC1.0.1
		    ln -s /usr/lang/SC1.0.1/f77
		    ln -s /usr/lang/SC1.0.1/as		(sun4 only)
		    ln -s /usr/lang/SC1.0.1/fpverison	(sun4 only)
	     4. Copy the "whatis" file from SC1.0.1/README to /usr/lang/man
		    cp SC1.0.1/README/whatis man/whatis

	  B. If FORTRAN 1.4 was installed into /mydir
	     (Non-Standard Installation )
	     1. Put the files into /mydir:
	            cd  /mydir
	            tar  xvf  /tmp/SC1.0.1_tar
	     2. Remove the soft links of f77, as and fpversion to /mydir/SC1.0
		    rm /mydir/f77
		    rm /mydir/as			(sun4 only)
		    rm /mydir/fpversion			(sun4 only)
	     3. Replace them with the soft links to /mydir/SC1.0.1
		    ln -s /mydir/SC1.0.1/f77
		    ln -s /mydir/SC1.0.1/as		(sun4 only)
		    ln -s /mydir/SC1.0.1/fpversion	(sun4 only)
	     4. Copy the "whatis" file from SC1.0.1/README to /mydir/man
		    cp SC1.0.1/README/whatis man/whatis

NOTE: If you have older binaries that are dynamically linked and you would
      like to run them such that they get linked in with these newer patched
      dynamic libraries then you can:

          setenv LD_LIBRARY_PATH /usr/lang/SC1.0.1
          or 
          setenv LD_LIBRARY_PATH /mydir/SC1.0.1

      so that these newer dynamic libraries are linked in.
