Just wondering why?

Why when I (setq TYPE "PVC80")
do my express tools stop working?
it doesn't seem to matter what I set TYPE to PVC80
or other material ie.stainless, carbon, ect.

 

if you use the VLIDE editor and type "TYPE" what color is it?

Just for fun, try (setq setq nil), that should kill just about any lisp
function.

Like any other language, you have to be careful about conflicting with
predefined symbol names or reserved words.

Technically, there are "thousands" of them as Doug says, but the vast
majority are longwinded "vlax-newfangled-mile-long-function-name" things
that you're never going to stumble into by accident. The more traditional
symbols are things like setq and nil, and there are far fewer of them that
you need to worry about.
