If you used the procedures included in the attached document then you
are making some mistakes in using usl/sl files.

The two obvious mistakes are:

1. You have created what you think is your new sl called slt. However,
you
   don't show that you ever rename the original sl file and then rename
   the new slt as sl. segmented libraries have the name 'sl'.

2. You haven't correctly managed the usl and subsequent appropriate
segment
   for the updated program. So, even if you got the sl correct you will
   still have problems. I cannot give you what to do because it depends
on
   the way the usl/sl files were managed and the naming convention of
segments.

I would recommend that you:

a. get a copy of the segmenter manual (docs.hp.com)
b. use 'listusl' against the large usl file to see how the segments are
   organized and use 'listsl' against the sl to see how the segments are
   organized. You should see the segments in the usl correspond to the 
   segments in the sl.
c. once you have learned about a/b then keep this in mind: you organize
your
   segment(s) as you want them in the usl file first and then your purge
the
   segment from the sl and then add it to the sl from the usl.
d. one final clue: every time you compile you get segments named
'seg#'... you
   can't be using these segment names or you would be trashing previous
changes
   every time you made a change to a different module.

good luck on your adventure!
