Set Color on all Nested Xrefs

[spm5]

I am pretty sure this can be done but I dont know VLAX commands well enough to do it. 

I want to set all the layers on all nested xref's to color 8. Does any know how/if this can be done?

Thanks.

[The (wcmatch) checking for "`*D*,`*X*" is to determine that an item is not a Dimension or old-style Hatch pattern "block" -- use string "`*D*,`*X*,`*U*" to also ignore anonymous Blocks.]

Overdid it a little -- the *D is only applicable to distinguish Dimensions when stepping through the "block" table [as in the routine I stole some of this code from], not when stepping through the entities in a Block definition [where Dimensions would not be "INSERT" objects].  That line can be:
 

    (not (wcmatch (cdr (assoc 2 (entget item))) "`*X*"))
 

and is only needed at all if you might sometimes encounter old-style Hatch patterns.  If not, you could set the 'found' variable with just this:

    (setq found (= (cdr (assoc 0 (entget item))) "INSERT"))

Your function is checking whether a Block Definition CONTAINS nested Block References.

My function is checking whether a Block Reference appears nested within another Reference.

Hence, for this task, you can use my function test whether a particular XRef has a nested reference.

I did misunderstand -- a semantic issue.  To my mind, the wording "a particular XRef has a nested reference" or "the supplied block name has nested references" means that it "contains" or "includes" one [or more] nested things within it, not that it "appears nested within another Reference" [for which I would use the wording that it is a nested reference].  If it really means the latter, forget anything in my replies based on the former interpretation, but just know that the meaning is not unambiguous.

But using the wording 'is a nested reference' is incorrect, since the block itself is not a reference and furthermore, not all references may be nested.

In my opinion, the function description is clear:

;; HasNestedReferences-p  -  Lee Mac
;; Returns T if the supplied block name has references
;; which are nested within other block references.
