Is it possible using DAQmx and LabVIEW to create a non-sequential channel task list such as \Dev0\Port0\Line0,2,1 to use as the "task in" to Create Channel ?
Or does each line number in such cases needs to individually have its Dev and Port prepended as in :
\Dev0\Port0\Line0, \Dev0\Port0\Line2, \Dev0\Port0\Line1 ?
I am aware that \Dev0\Port0\Line0:2 can be done if sequential

I meant to say
It seems that an array must be built such as :
and then use DAQmx Flatten Channel String to produce a single string with comma separated lines, each with its device and port prepended.
I found it not possible to include the same line number more than once in the task list, although for analog input that is acceptable.

To use lines in the order 0,2,1 does not require specifying
"/Dev0/Port0/Line0, /Dev0/Port0/Line2, /Dev0/Port0/Line1"
Since the last two lines are sequential, it is sufficient to instead just have :
as learned by examining the output of DAQmx Flatten Channel String from the array :
I would have hoped/liked/assumed that if DAQmx can accept and figure out how to use a specification of .../line0:2 that it would also be able to take .../line0,2,1 and similarly apply the preceding /Dev and /port specification and apply that to any lines after that.
