SOS is described in SOS.LES[S,DOC], and briefly below:
To create a file (a program, a writeup, or whatever),
first be sure you're at monitor level (type CALL on a display
or <control>C on a teletype), then
type "CREATE file.ext" where "file.ext" is the file name and extension
that you want the file to be called (be sure to end this command
with a carriage return). After SOS types a line
number (starting at 00100) you may
start typing whatever is to go in that file.
When you're finished and want to save what you have, type
carriage return to finish the line you're on, and then type
alt-mode (ALT, ESC or PREFIX on a TTY, or <control><shift>K).
SOS will type an asterisk after you type alt-mode. SOS will
now accept any of the following commands (all commands are
terminated by a carriage return):
P<line number> Type the specified line
P Type the next 15 lines
I<line number> Insert text starting at
the specified number.
To leave Insert mode, type
alt mode.
I* Insert at the end of the
current page.
D<line number> Delete specified line
W Write the file. Saves it
in case the system crashes
E Exit - save the file and exit.
To return to editing the file after you exited, type "EDIT file.ext"
SOS will type an asterisk and the commands above are valid.
[Note to system programmers and all users -- SOS has one bug,
namely that if your default file protection is nonzero, the CREATE
command causes your new file to have protection 000 instead of
the correct default. Users who want to protect their files
from being deleted by random users should explicitly
change protection immediately after creation, or if tolerable
use UFD protection instead of default file protection.]
