You are using different terms from what we are used to, this is why
everyone is asking you to clarify. Let me take a few guesses as to what
you are wanting.
1. I want to acess the memory where a numeric is stored.
If you want to do this because you are going to call a DLL, passing in
the value and having it return with possibly a different value, then the
DLL configuration dialog lets you pass numerics to external code by
pointer to value.
2. I want a way to access a numeric control or indicator from other
places in my application, so that I can do UI things such as
enable/disable, change color, change value, etc.
In this case, you want to use the control referen
ce. Popup on the
control and Create a Reference. The reference can be wired to property
nodes, invoke nodes, passed to subVIs that work on the properties, etc.
3. I want a pointer or reference to a numeric value so that I can
access it in many places in my program, or store the pointer in a data
structure such as a list.
These are ideas that do not really get along with the LV dataflow
paradigm. Instead, you should just pass the value wherever you like.
If multiple program locations need to access or modify the value, you
can arrange for them to do so via a functional global, a queue, or if
they only need sequential access via an in/out parameter.
As with the other responses, if none of these are sufficient, please
clarify the question.
