Thanks again Sideway.
I have modified yours perfectly working code to work with V130.
I also used INVERSE bit to see which MB you are toggling.
The only downside of this method is, that you have to have LINED UP MB's.
For example MB0 to MB7.
You can not have for example MB1,MB2 then MB8,MB9 and MB33, MB34.
Thanks again for yours excellent idea.
