Many threads on many forums dedicated to options for loading lisp. First thing would be to keep all your lisp in folders in the Support File Search Path to avoid ever having to include paths like that.
Having a large number of lisp loading every time you open a drawing you may not need seems unnecessary.
You seem to have 10 lisp listed for setting scale. Why not use one lisp with an argument like
(defun scale1to (x / temp)…
where
(scale1to 50)
would replace the macro for 1-50.
Consider using the lisp function
autoload or just have it autoload in the macro like:
(or (scale1to)(load "scale1to.lsp")) (scale1to 50)
which would load the lisp if it wasn't already loaded and then set the scale to 1:50. This is how 90% of mine are loaded.
