This program goes with the tktn mod elsewhere on this tape.
It finds all tasks active on the terminal with a few
exceptions and goes into system state and performs an abort
(so it can set up a new abort code). All tasks are aborted
on the users terminal. No notification is given if the tktn
mods are installed. If not, then this task could crash the
system (but I don't know for sure). The abort code could be
changed to that which the mcr abo command issues if one
does not want to modify tktn.

We run a local command line interpreter task called ...jpl
There is thus a check for any task which is called jplxxx
or xxxjpl running on the terminal and skip the abort for
that task. This may be nop'd or changed to suit your
environment.

This program is built using the MP macro processor
(elsewhere on tape) However, the macro-11 output is also
supplied and it may be built directly from kill.mpp.

Look at kill.cmd to preprocess, assemble and build it.
However, you most likely will have to do it manually unless
you have the /prm install patch and have also built the MP
processor.
