Hello I have a situation which I will try to 'best' describe below:
1. In one of the Event cases in my Main vi, I have LV code which executes a test that includes setting certain H/W and reading various instruments. 2. This execution in (1) executes a vi that is down as follows Main->sub1->sub2->sub3. 3. From sub3 I would like to pass some info up to Main where I want to display that thru an indicator, to a user. 4. What would be a good way to do this, given the constraint that I prefer to avoid wiring from sub3 all the way thru to Main? I would like to feed back this info as the sub3 changes it and still in execution. Want to avoid wiring since I already have so many I/O terminals being used(yes, even after clustering) on the connector pane. Is there a way to do this using refnums between the main and sub3 without having to go thru the intermediate vi's? Is there a way to read the output of a connector terminal of sub3 directly in Main? Something I saw in an LV manual about strictly typed VI, call by reference node etc, that I saw but not fully clear on. Thanks for any tips & ideas. Khan Kabir Xerox Corporation Rochester, NY
