@begin(itemize)
Files under C:\usr\lib\samples and the sample directory itself
have been been deleted.  (Sample programs are located in \usr\src.)

The file @i(gks.h),  a new C header file was added to C:\usr\include .
This header file should be used for GKS applications written in C.
@begin(format)
#include <gks.h>
@end(format)

The GKS demo's written in C located in C:\usr\src\gks have been
updated and recompiled to include the new header file @i(gks.h).

You can now compile C programs that call GKS with the @i(cc) command.
@begin(format)
cc @i(sourcefile).c  -lcgks -lgks
@end(format)

You can now compile C programs that call the @i(curses) library
with the @i(cc) command.
@begin(format)
cc @i(sourcefile).c  -lcurses
@end(format)

You can now compile Professional Fortran programs that call GKS
with the @i(f77) command.
@begin(format)
f77 @i(sourcefile).for	-lpfgks -lgks
@end(format)

The @i(f77) command now lists errors by default.  If you wish the error
listing to be a file rather than sent to the screen,  redirect standard
output.
@begin(format)
f77 @i(sourcefile).for	> @i(listfile.ext)
@end(format)

All 20/20 tutorials will now work.

The \dev\netdev.sys file used with the PC/IP networking package
is now by default set to NULL,	an invalid network address.
When the AT is connected to the network,  call
the Athena service hotline at 3-1410 to arrange for a correct
\dev\netdev.sys file.  Warning:  If two people try to @i(telnet)
using the same network address,  the AT system will hang.  Do
not customize \dev\netdev.sys yourself.

The @i(lpr) command's @b(-P local) option to select a printer
hardwired to the AT now works,	provided that the AT system @i(PATH)
environment variable has not been changed since the AT System 2.10
was installed.

When you use the @i(lpr) command to print on a remote printer,
the output will be followed by a formfeed.

The SAFE command with the -c and -s options will now work on any size
directory tree.

The command @i(ATHENA) has been renamed to @i(AWVER).  This command
returns the version of the AT System that the AT
Workstation is running.

A general cleanup of files within the the system directory heirarchy
was done.
