for loop indexing?

[Sergey Yakovlev]

Is it possible to change indexing step in labView "For Loop" structure? By
default this value is 1, and I need to make a step value different from "1"
like in C example:

for (index=0; index < 100; index++) {}; // step=1
for (index=0; index < 100; index=index+3) {}; // step=3

All you have to do is use the while loop instead of the for loop, you can have any increment value that you want. Terminate the while loop when some test condition is reached.

Or do the for loop from 0 to 33 (N=34) and use i*3 as index.

Sergey,
To step by count of 3: Add a shift register pair to your for loop. Initialize the left register to 0. Wire the left shift reigster output and a value of '3' into an Add vi. Send this sum to your right shift register (for use in the next loop) and also send it out as needed for your application. This will be an increment of 3 for each For loop.

I just noticed Dennis has given a workable method with while loops, so now you have 2 options.

Good luck with it, Doug

What about
j:=i*3
and i is incremented by 1
