Meh I'm with crossrulz some times.  If I were looking for a Fletcher Checksum VI I know I could do it,

You could do, but that is not the point.  The OP didn't even bother trying.

I increasingly see a lot of laziness on these message boards.

People expecting to be given something without even attempting to make an effort.

I have always learned more by doing than getting a handout.

It is easy to get jadded on the forums.  I wonder if we need a support group.  Maybe a dedicated subforum for people to say thanks, and give stories of how they went from zero to hero because of the direction and help of experts.

Fact is uncomfortable for some people.

I never said anything about being uncomforable, and I didn't say anthing about denying facts.

I finally do one myself that work like I need. This is the VI:

The case structure is is for adding zeros if necessary (it takes the digits in groups of four)

You should have stated that you wanted a U64 as the input.  And then that you just wanted the lower non-0 16 bit words.

You have plenty of Rube Goldbergs in there.  For instance, change your Scan From String to output a U16 and you can simplify your combining of the sums to a simple Join Number.  You could also make the format for the string be %4x.  This would eliminate the need for the String Subset since you could just keep the remaining string in a shift register.

And your adding of zeros I think is done at the wrong place.  They should be added to the front of the string, not the back.

And building on the code I already gave you, here is a much smaller version of the code that does the exact same thing.
