For me it was the most time consuming D-CLAD for the last months, so I had to change from a “help file based” approach to a “real coding with LabViEW” Approach:

1-b         I guess the function Read Delimited Spreadsheet was designed for such purposes. So no further explanation necessary.

2-c          Important is, the Read File function reads the whole content of the file in the first Iteration and returns an empty string in the second iteration. The carriage return Linefeed symbol located in the lower right corner means “Convert End of Line” and NOT Read “line wise” as I thought first. For the output, only the second iteration is relevant. So the output array should be empty.

3-a         During the last iteration once again we read an empty string. With this output tunnel only answer A) makes sense.

4-d         Because Steve printed an D close to the output 😉
