Hi All
I still dont understand about working variable in Action Block.
Anyone can teach me and make an example about working variable of the simple action block.
Thanks for your help

It's a way to control the visibilitly/scope of the variables.
Working variables are a way to have variables used by an Action Block, but not visible outside the Action Block.
Prior to the new working variables feature, any variables used in an Action Block were visible in calls to the Action Block. The problem with that is that it cluttered up the Action Block call -- the Action Block might actually only return a single value, but all of its internal working variables would always be listed, e.g.


Now you can make those variables visible only within the Action Block. It makes calling the Action Block less messy.

Thank you so much. I understood more clearly

They are just temporary local variables that can be used for intermediate calculation values without having to abuse output parameters for this purpose.
