Has anyone got something like this WITHOUT all the VLA-* calls? (IE something that'll work on older versions)
"ACAD_LAYERFILTERS")))

which older versions? AFAIK, versions that can't use vla-* don't have the named layer filters either.....

In "older versions" you will not find any layer filters ;-)

What about 14? It came with LMAN, but if I remember correctly, those VLA-* calls weren't supported yet. I may be wrong, I'm a bit fuzzy on those "extended" LISP commands. Once upon a time they were something, they changed them to something else.....
While I'm at it, if anyone could clear up the history of those commands, say with a link, I'd also be grateful.

In Rel. 14 you can create only ONE Layer filter at one time... Or I'm missing something?

Michael, As Jurgen pointed out, with rel. 14 you can create only one layer filter. You CAN create layer states that are saved to file, but that is not what this thread was referring to, or at least that's what I thought ;-)

commands, say

So I'm TOTALLY CONFUSED? Sorry. I thought we were talking about a routine to delete those nasty named layer states that can only be selected one at a time for deletion. You were talking about filters applying to the layer dialogues?

No, Jurgen. Ithink I was missing something: the whole point of the thread. See response to Jeff.

And here is a modified version that asks for the names to delete, wildcards are allowed.
