Well guys and gals,indeed it was a simple settings oversight. You are both right,and it is located in menu/keyboard/ensemble/joystick pedal. I can choose where I want the sustain active,as Don said.
There is no lock per se,but saved in SB if desired. I have added sustain to "My Setting",but still on a reg to reg basis. That's okay, I know how to handle it now.

Thank you for the time spent trying to help this old guy.

Great to hear you got it sorted Bernie.
