There are 5 lessons on running SED:

    1) Introduction to SED and writing a file with SED
    2) Parameters, moving through the file, inserting and deleting
    3) More on moving through the file, searches, copying and moving text
    4) Advanced SED editing
    5) Useful commands for special cases

%TEXT
It is not recommended that you take all 5 lessons in one sitting.
It would be best to practice the material learned in one lesson
before going on to the next.
However if you must take several lessons at a time, please limit
yourself to the first three; they are enough to give you a good
solid understanding of SED.
%TEXT
It will make things a lot easier for you, when you run the lessons
if you get a copy of "HLP:SED.HLP" or one of "TED:SEDM2A.KYS" (for
MIME-2A) and "TED:SEDV10.KYS" (for VT-100).
To print out these files, type the monitor command:

        PRI filespec

where "filespec" is the name of the file you are interested in.
