a question on while loop

[Guohua Jing]

i use while loop to realize some analysis, and want to
show the results of each iteration. I just put a digital
indicator outside of the while loop, however, no results
appear, but if I just move the indicator into the loop,
then everything works fine.

If you put the indicator outside, it won't show anything until the loop is complete, and if you put it inside, it will show eah iteration result, deleting the previous one. If you want your data to be shown each iteration mantaining previous ones, you should use a shift register, and wire it across build array, adding inside data to it. This way you'll have a size incrementing array showing all results as they are created. You of course have to wire the shift register inside the loop.
Hope this helps

If you are using Build Array in this way, you must right click on it and select Concatenate Inputs.

Why not just enable indexing? Unless he really wants to the values while
he's still in the loop...

You can use Control Refnums and Property nodes to view things out side a
while loop, while it is running. This is the new feature(of encapsulation)
of LabView 6i, but I have to tell you that it is somewhat complex and took
me a few days to get to understand all this stuff, especially since I'm
still hands on learning. But I think this is a great feature of 6i.
