BEWARE FILE FOR THE SED SCREEN EDITOR

SED %2(661)

SED, on  TOPS-10  only,  now uses  the  PSI system  to  intercept KSYS
countdown interrupts. The symbol, KSYMIN, in SEDSYM is set to 10 (ten).
This symbol is used to determine the when SED should start warning the
user of the impending KSYS. E.g. KSYMIN=^D10 means starting at 10 minutes
till KSYS, SED will start warning (message at bottom of screen) the user.

PUSH command has been implemenented for TOPS-10 7.03.

SED now supports VT200 series terminals. See SEDV20.KYS for keyboard
layout.

SED %2(656)

   SED  runs on any processor that runs TOPS-10 or TOPS-20. However, if
you have a  KA-10  set  the  assembly  parameter  "FTKA10"  in  SED.MAC
(FTKA10==1).

   SED  currently  reads  the file to be edited into core and writes it
out on exit.  This  limits  the  size  of  the  edit  file,  the  exact
restriction  depending on the system's memory and virtual memory.

   If you define both the current file and the alternate file to be the
same  file,  when  you do SET-FILEs to toggle back and forth the cursor
may not be where you left it. (no harm is done, though).

   If  your  terminals run at 9600 baud you may have a problem with the
terminal sending XON-XOFF pairs when it feels  overworked.  SED  has  a
hard  time distinguishing those characters from the ^S and ^Q commands.
The easiest solution is to avoid using ^S and ^Q as  commands  and  set
the  NPG flag to tell SED to keep TTY PAGE in effect (read SED.MEM, the
installation guide, if you don't understand  this).  See  the  keyboard
layout  in  SED2.KYS for a suggested arrangement of keys which does not
use ^S and ^Q.
