Extracting arrays from cases, 2nd try

Question

Hallo,
since my first trys of this topic was unclear, I try it again:
I have a case structure with two cases:
case 1: 2D-arrays, case 2: 1D-arrays and Strings
In the two subcases you have another select case -- structure with various cases:
case 1: subcase 1, subcase 2 etc.
case 2: subcase 1, subcase 2 etc.
I want to save the arrays and the strings to one text-file. How can I do that? If I connect a wire to one of the arrays, the VI doesn't run because of a "tunneling error" (missing assignment to tunnel).
I know how to write arrays to a file, my problem is getting them out of the case-structure.
Hoping fr help,
Arno

Answer 1

Hallo,
>> Since Case 1 and Case 2 output different data types, you cannot put them on the same wire. Why don't you put the save operation inside the case structure, in case 1 you save the 2D array and in case 2 you save the 1D array and strings. <<
That works (I already tried), but I cannot use that idea because of two reasons: First, I want to save all the arrays and strings to ONE file in an order I decide. Second, the VI should do that with approx. 10 arrays / strings and that 100 times for 100 files. Working with temporary files is not possible.
>> Alternatively, you can convert your data in each case to the final string result to be saved, which you then can save using write characters to file at a later point in the code. Since only a
string leaves the case structure, there is no data conflict. <<
My problem is not a data conflict (arrays, strings etc.) but getting the data out of the case-structure. I don't even get a simple string constant out of it.
To make my problem clear, I attached a simple (not running) VI. "Your task" is getting the data out of the structures.
