(On holiday at the moment so a limited reply.)
Well what should have happened until bash version 4.4.5 and what actully happens is not the same.

Code:

#!/bin/bash
bash --version
uname -a
status=0
KEYBOARD()
{
	read -r -p "Enter QUIT or EXIT to quit:- " kbinput
	if [ "$kbinput" == "QUIT" ] || [ "$kbinput" == "EXIT" ]
	then
		status=255
		break
	fi
	if [ "$kbinput" == "TEST" ]
	then
		echo "Hello World!"
	fi
}
while true
do
	echo "This will loop and hold until keyboard input is quitted."
	KEYBOARD
done
echo "You are here..."
echo "Status = $status..."

Resukts:-

Hello World!

Enter QUIT or EXIT to quit:- EXIT

Status = 255...

This is the same on bash version 4.3.42.
The status is/was exactly as I want it except I have changed the code now whilst away on a break!
Will be home again soon and get back to you fully...

command-not-found

COMMAND-NOT-FOUND(1)					    http://en.opensuse.org/Sco					      COMMAND-NOT-FOUND(1)

NAME

       command-not-found - A command-not-found handler

SYNOPSIS

       command-not-found {binary_name} {repository}

ARGUMENTS

       The following arguments are required:

       binary_name
	   The name of binary you are looking for.

       repository
	   The name of repository for search. For most cases, use zypp

DESCRIPTION

       command-not-found handler is designed to tell users which package contains a missing command.

       The handler is integrated to bash(1) and zsh(1) shells and is not necessary to call it directly. Just type a name of the command in your
       favourite shell and you'll get a result.

       If you consider c-n-f handler useless, just add unset command_not_found_handle to your profile or remove the command-not-found package.

       Handler doesn't call the command-not-found binary directly, it only prints info about it. If you want to invoke it automatically, just add
       export COMMAND_NOT_FOUND_AUTO=1 to your bash profile.

EXAMPLE
: NORMAL USAGE
       For example you want to try blender, because you have heard that is an amazing program. So just type blender in shell:

	   $ blender

       You get the following output:

	   The program 'blender' can be found in the following package:
	     * blender [ path: /usr/bin/blender, repository: zypp (openSUSE 11.1-0) ]

	   Try installing with:
	       sudo zypper install blender

	   bash: blender: command not found
