How do I create a struct in LV?

[5thGen]

I am trying to create the equivalent of a struct within LV.  I believe using a cluster is the route to go but I don't have much experience with them.  I would like to define and initialize a group of variables and then reference them by name further along in the code.  Any suggestions?

Thank you,

Stephen

Oh man.... another text programmer

I'm just kidding.

You can bundle the 'variables' into a cluster.

Then you can reference the cluster later in the code, and unbundle it to access the various parts.

char message[5]={'T','h','a','n','k','s'};

for (i; i <=5; i++)

{

    Write(message[i]);

};

Just kidding.  Thanks for that, I was trying to get this to work yesterday but it kept unbundling with only one name (the first variable placed in the cluster box). It was happening because I needed to name the rest of the variables before unbundling the cluster.

When you use the 'unbundle' function, it should automatically resize itself to display all of the components.

Hi,

either resize the "unbundle by name" function to show more/all cluster elements or use the simple "unbundle" function which always shows all elements (but not by name).Or click the element name in the "unbundle by name" function to select a different element...

And please try to use LabView names (cluster instead of "struct", cluster element instead of "variable") as it will be a lot easier to understand your question and to provide help

STRUCT => CLUSTER;

it is usually best to make your clusters as typdefs and use bundle/unbundle by name

which is like

struct.field = value    this is bundle by name.
