Understanding an NDR wide char string

[Scott Warfield]

The reference I mentioned defines the format label as a header which defines
the data represented, ie, an int, float, etc.  I'm just starting out with
NDR, so I'm kind of making assumptions.

That would be a wchar_t * with a [string] attribute.

What exactly would this field do? Other then that, your comments look ok.

Character would not necessarily be at this position but might be deferred
(if the wchar_t * is embedded).

What exactly do you mean by 'format label' ? The example here would match:
[string] wchar_t data[] or wchar_t *data if there is no other data after
data.
