I have successfully used a 1990 version of CHTEXT.LSP by Yoder
but recall a newer file of the same name that did not work.
I believe most Lisp programs written for Acad12-13 will function
verbatim, or with very few modifications,(except those dealing
with SOLIDS). Acad14-2k+ Lisp files present a greater likelihood
of incompatibility.
There are a lot of free Lisp libraries available on the WEB.
Download some and try 'em.
