HOLY DEFUN'S BATMAN!!!
I ran through it quickly in Notepad++ and found that there were allot of extra "'s in the file that would cause an error but I think the main failure was in this:
; MEP-hatch with the ANSI31 pattern
;
(defun C:ARJOHATCH (/)
(C:SAVELAYER)
(setq
"dmscl2" (/ (getvar "DIMSCALE") 2) )
(prompt "Select Entity To hatch:")
(command "hatch" "ansi31" dmscl2 "0" pause "")
(C:RESETLAYER)
(princ))
I removed the ""'s from the var and it loaded fine
Here is the file, it seems to load fine I did drop some of the line to a new line so that the whole line would show in my editor.
