Select Node Wish

[alphaone]

The following diagram is not efficient, thought we can use "Select Structure", i hope some improvement on "select node" that pre-judge which branch will be executed.

BTW, i hope the "hot-key" for the popup menu on diagram.~~ i like use the keyboard instead of mouse click~.

alphaone,

I'm sorry, but in Labview, the way you have diagramed it, is the "Basic" equivalent of:

i = 0

j = 0

for k = 1 to 100

next k

input l

if l = 1 then m = j

else m = i

no matter how you cut it, you still get zero, but no matter what you do you have wasted 100 loops getting nowhere...

However, if you want to branch and conditionally decide if you want to go nowhere FAST or nowhere slow, the folowing diagram will get you nowhere at your desired pace.

Liiva,

Well, the for loop is just a example as "doing some time-cosuming job", i don't care the result. I mean that I don't hope the useless operation on the useless branch. It's better that the "select node" judges the condition first, then select one branch to operate,just like "Select Structure".

Thanks:)
