Hi, I have a sub-process where I am spawning multiple instances. It is set

Hi,
I have a sub-process where I am spawning multiple instances. It is set to run all instances at the same time.
For each of these instances, I am passing the output to a variable on the main process that is boolean and set to multiple (pv!isClosed).
I want to check that all the instances returned true and use that in an XOR gateway to determine the next path in the process.
What would be the best way to do this? Would that output variable be overwritten by the most recent instance that ran or can I use the tp!instanceindex to reference each output of each instance? I was looking at the all() function as possibly a way.

Thanks
Gary

One option would be to append the output of the sub process to a Boolean array (instead of a single Boolean) and check via where() if any of the array element contain false() within a XOR gate

Hi Sathya,
OK, I have output to a boolean array. Should i use the all() function to check the array?

You can try something like .....contains(pv!isClosed,false) and if you get output as false which means all the instances has returned true,.

Perhaps just use the and() function on the boolean array.

hi normanc, for the and() function what would I use for the expression or function rule to check that the value is true
