mhupp,
Your suggestion and generous code submission are both very well received: Thank you!
I will rework the "robot" program code to include your superior code lines.
Questions
Outside of the important warning applied to LISP programming and variables,
Can you or others give an example(s) of instances of how a programmer/customizer can modify default commands?
Would this action be limited to creating macro code lines to assign to custom buttons?
Future
After stalling out, I am now at a DWG-based design environment and will resume my LISP programming studies. I was recently encouraged by understanding how to use the built-in IDE.
P.S.: My thanks go out to the excellent developer and programmed systems just developed from a longtime fellow member of other forums and entrepreneur running https://cadprograms.ca/
Thanks,
Clint
