Just curious if there is a known way to gather the entire contents of a global variable list as opposed to individual reads or subscriptions?

for Instance, instead of subscribing to "n=2,s=Application.myVars.someBit" , just doing a general subscription to the the entire list "n=2,s=Application.myVars".

Just trying to learn/improve.

Thanks in advance.

Used the browse node, and this is solved.

would have helped if I was using the right syntax for reading nodes. 😛

"ns=2;s=Application"
