(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!
This will loop and hold until keyboard input is quitted.
Enter QUIT or EXIT to quit:- EXIT
You are here...
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...

pvmfarchcode

ARCHCODE(3PVM)							  PVM Version 3.4						    ARCHCODE(3PVM)

NAME

       pvm_archcode - Returns the data representation code for a PVM architecture name.

SYNOPSIS

       C    int cod = pvm_archcode( char *arch )

       Fortran	 call pvmfarchcode( arch, cod )

PARAMETERS

       arch    Character string containing the architecture name.

       cod     Integer returning architecture code.

DESCRIPTION

       The  routine pvm_archcode returns an integer given an architecture name.  The code returned identifies machines with compatible binary data
       formats.  For example, SUN4 and RS6K have the same code, while ALPHA has a different one (because a few datatypes  have	different  sizes).
       This  lets  you	know  when you can get away with using PvmDataRaw instead of PvmDataDefault encoding to pass messages between tasks on two
       machines.

       Naturally, you shouldn't assume the values returned by pvm_archcode are etched in stone; the numbers have no intrinsic meaning except  that
       if two different arch names map to the same value then they're compatible.

       This  routine  is  actually  obsolete  in  the sense that the architecture codes returned are already available in the hi_dsig field of the
       pvmhostinfo structure returned by pvm_config(), as shown in the below example.  The routine is maintained for backwards compatibility only.

EXAMPLES

       C:
	    struct pvmhostinfo *hip;
	    int i;

	    pvm_config((int *)0, (int *)0, &hip);
	    i = pvm_archcode(hip[0].hi_arch);

	    /* or you could just do:  i = hip[0].hi_dsig;  */

       Fortran:
	    CALL PVMFARCHCODE( 'RS6K', k )

ERRORS

       On success, pvm_archcode returns a positive integer data signature.

       The following error conditions can be returned as well:

       PvmBadParam
	      giving an invalid architecture name.

       PvmNotFound
	      there is no host with the given architecture name in the current virtual machine configuration.

       PvmSysErr
	      pvmd not responding.
