Allocate 15 different variables with one internal variable

Allocate 15 different variables with one internal variable

Hello,
I am trying to allocate 15 different variables with one internal variable. All variables are boolean. If one or more variables of 15 will get value True then internal variable's value also will be set to True. If one or maybe more of the 15 variables' values become False, the internal variable's value will be still True until all 15 values will be False, so then internal value will be also set to False.
I don't know how to do that :(
Thanks in advance.
