Yes quite right,

Yep, just got a copy of "Software Testing", Ron Patton, SAMS 2000
(really good book) I was trying to write a crude script to try and break
a beta program in different ways.

Yep spotted that just after I posted

Believe me when I say Doh! I should have spotted that. The other two
changes I wouldn't have worked out so cheers for that. (cheers mick too)
Looking it up I see -lt stands for less than. Must be getting my
languages mixed up.

It works but the process isn't killed. Would you like some tomato sauce
on that cat? :-)

I get this kind of output:

(~)> ./testscript.sh
Starting Run
./testscript.sh: line 18: =25213: command not found
kill: usage: kill [-s sigspec | -n signum | -sigspec] [pid | job]... or
kill -l [sigspec]
Program has been run 1 times
./testscript.sh: line 18: =25216: command not found
kill: usage: kill [-s sigspec | -n signum | -sigspec] [pid | job]... or
kill -l [sigspec]
Program has been run 2 times
./testscript.sh: line 18: =25219: command not found

It's not echoing the PID correctly. This is my current code:
-------------

#!/bin/bash

echo "Starting Run"

opens=0

while [ $opens -lt 5 ] ; do
        viewer &
        $proID=$!
        sleep 10
        kill $proID
        opens=$(($opens+1))
        echo "Program has been run $opens times"
done

--------------

doing 
        kill $!
instead of kill $proID didn't work,
nor did putting gaps in
        $proID = $!

(~)> ./testscript.sh
Starting Run
./testscript.sh: line 18: =: command not found
