     I assume that you have a binary installation.  You need to put in
your .cshrc, .tcshrc, or .bashrc file (depending on what default shell
you use), a line to define $AIPS_ROOT and a ref to its login.  Thus
for tcsh and csh

   setenv  AIPS_ROOT   <path to main aips location>
   source $AIPS_ROOT/LOGIN.CSH

or for bash

   export AIPS_ROOT=<path to main aips location>
   . $AIPS_ROOT/LOGIN.SH

This should allow the $LOAD to be recognized and the LD_LIBRARY_PATH
needed to actually execute the programs.

Surely you can do a

   ps -elf | grep TPMON

and then

   kill <process_number>

or is needed kill -9 <process_number> for the <process_number>'s seen
by the ps command.  If you cannot kill them then identify who started
them and have him or her kill them.  Actually this is not too
important.  I added more messages to TPMON so that we can diagnose
problems with tapes better.  In the absence of errors that is not
important.
