800xA AC800m: What's the point of using the retain attribute for structured variables such as BoolIO?
Is there any reason to set the "retain" attribute for structured variables such as BoolIO? I don't see the point, because all of the components of the BoolIO variable (Value, IOValue, Forced, Status) have the retain variable anyway.

No point In case of BoolIO. Can be useful when any one component in structure variable is not set to retain as shown in picture below. Var2.Var1 will not be retained while Var1.Var1 will be.
