Files under C:\usr\lib\samples and the sample directory itself
should have been deleted.  They
are empty; ignore them.  (Samples have moved to \usr\src.)

You cannot compile C programs that call GKS with the @i(cc) command.
Instead, use:
@begin(format)
lc1 @i(sourcefile).c  -ml -s -b
lc2 @i(sourcefile).q
link  \lib\c @i(objectfiles), @i(outfile),, \lib\cgks \lib\lcm \lib\lc \lib\gks
@end(format)

Always link to the C math library @b(before) the regular C library.

The @i(f77) command does not list errors by default, and the help
for the command omits the options that create the error listings.
Add the options explicitly:
@begin(format)
f77 -LE @i(sourcefile).for
@end(format)

You cannot compile C programs that call the @i(curses) library
with the @i(cc) command.  Use the @i(lc1), @i(lc2), and @i(link)
commands instead.

One of the tutorial options in 20/20 will fail.  To fix it, first
enter:
@format{
\etc\attrib  -r  \usr\lib\2020\total.tut
}

The \dev\netdev.sys file used with the PC/IP networking package
is set-up WRONG.  Two people trying to @i(telnet) at the same
time will hang because both have the same 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.

The @i(lpr) command's @b(-P local) option to select a printer
hardwired to the AT does not work.  Use PRINT instead, temporarily.

When you use the @i(lpr) command to print on a remote printer,
the output comes out without form feeds at the end.

The 1600 byte environment space tends to overflow.  Use it sparingly.  This
is particularly acute for people who use @i(telnet) because
escaping out of @i(telnet) creates a new copy of the command.com file
instead of using the old.

If you use the SAFE command with the -c and -s options on a large
directory tree it will fail.  Use SAFE in pieces on smaller parts
of the tree.
