The script uses a table to review the event and make a determination. This way if you ever need to add another event just add it to the table and be done with it, no code changes required.

## Purpose: kill all messages other than those specfied in the arg list
##
## UPoC type: tps
## Args: tps keyedlist containing the following keys:
## MODE run mode (“start”, “run” or “test”)
## MSGID message handle
## ARGS user-supplied arguments:
## DEBUG: determines weather we recieve all of the echo commands.
## Use this syntax for new echo statemtents: if {[debug == 1]} {
#echo “DEBUG($myprocName) -MESSAGE “}
##
##
##
##
##
## Returns: tps disposition list:
