document's namespace.

Look at AutoLISP Reference about " vl-doc-set"

Sets the value of a variable in the current document's namespace.
(vl-doc-set 'symbol value)

This function can be used by a VLX application to set the value of a
variable that resides in the current document's namespace.
If executed within a document namespace, vl-doc-set is equivalent to set.

I am not yet understand,what is the meaning "document's namespace"?

then look at sample;

_$ (vl-doc-set 'foobar "Rinky dinky stinky")
"Rinky dinky stinky"

_$ (eval foobar)
"Rinky dinky stinky"

I thought "(vl-doc-set 'foobar "Rinky dinky stinky") " same as with (setq
foobar "Rinky dinky stinky") !!

 

Look for a word "blackboard" in help

When you create a .VLX you have an option of creating all the named functions
and variables in its own namespace separate from each document's namespace. To
expose your functions/variables to any document's namespace you would need to
use such vl-doc-*, vl-bb-*, and vl-acad-*defun functions. I suggest you study
the acad_dev.chm help file.
