No Auto-concatenated strings in a (For / While) Loop ?

[Ettepet]

I saw that "auto-concatenated" was added to the Tunnel-mode of a For Loop.  I was positively surprised as it looked very convenient to put it directly into use.  However, the string characters I wanted to concatenate caused an error.  Upon looking closer at this recently added feature I saw that it could concatenate arrays only.  Of course I can convert the string into a byte array and (afterwards) back again, but it seemed an omission which might be added in a new Labview version.

Hi Ettepet,

you probably know you can do this easily like this:

I think issue may be because string lenght is not fixed.

For loop preallocates the memory locations for arrays depending upon the datatype.

But because of variable string length it will be difficult to implement in for loop. ( ofcourse concatenate and build array function do not preallocate memory )

Of course.  But what does it do? 🙂  Couldn't even find the function you use after the Loop (unless it is squashed).

Hi Ettepet,

my picture is a snippet.

Btw. that function is ConcatenateStrings...

@Neos:

You surely can concatenate arrays of varying length in the loop. So that shouldn't be the problem. Concatenation is memory-inefficient anyway, regardless of using a (new) output tunnel or the "traditional" way of BuildArray or ConcatString...

Ah, easy really. 😉

If a Loop in Labview needs to have "preallocated memory locations" and for that reason excludes variable length strings then it is clear.  There already was the fact that single character strings don't exist as an enitity so there would be no natural progression from "indexed" to "Auto-concatenated" like there is for elements and "arrays of elements".

GerdW,

The original question was if the conditional index option is working for arrays so why not for strings.

I am sure original poster knows how to do things ( myself also )

May be you missunderstood ( or me )

No disrespect

The original question was about  "auto-concatenated"...  😉
