Here is how I load my routines "Arch Program":
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;;
;;; Following is a list of AutoCAD, Express Tools, and user-defined files in
;;; the order they are loaded when you first start the program. Go to AutoCAD
;;; Help and search for "support file loading" (including quotes) and the
;;; top result is "Order of support file loading" which nets the following:
;;; <File For:> <Use By:>
;;; acad2000.lsp AutoCAD
;;; acad.rx User
;;; acad.lsp User
;;; acad2000doc.lsp AutoCAD
;;; acetutil.fas Express Tools
;;; acaddoc.lsp User
;;; mymenu.mnc User
;;; mymenu.mnl User
;;; acad.mnc AutoCAD
;;; acad.mnl AutoCAD
;;; acetmain.mnc Express Tools
;;; acetmain.mnl Express Tools
;;; s::startup User
;;; Note: If the user-defined function S::STARTUP is included in the acad.lsp or
;;; acaddoc.lsp file or a MNL file, the function is called when you enter a new
;;; drawing or open an existing drawing. Thus, you can include a definition of
;;; S::STARTUP in the LISP startup file to perform any setup operations. For more
;;; information about the s::startup function, refer to the Customization Guide.
;;;
;;; It should be noted that Autodesk's website is misleading about the load order.
;;; The menus load in the order they were initially loaded in, and *not* always
;;; the user menu first. The only way the user menu loads first is if all menus
;;; were removed and the user's menu was loaded first, then the other menus
;;; subsequently. In most cases people tend to leave Acad's menu there, then
;;; Express Tools (if installed), and then finally the user's menu.
;;; This can be verified by watching the menu load prompts:
;;; AutoCAD menu utilities loaded.
;;;
;;; Key files to needed to run this program:
;;; (1.) The "ACAD.lsp" file sets the path for the arch program along with the saved autocad
;;; environment settings for a clean restore to generic autocad when the arch program
;;; is unloaded. This is the only file that must be located at each workstation within
;;; the autocad support directory. It only loads at AutoCAD startup.
;;; (2.) The "ACADDOC.lsp" loads the "ARCH_INITIALIZE.fas" file.
;;; (3.) The "ARCH_INITIALIZE.fas" initialize the setup.
;;; (4.) Custom settings are controled by the "custom_xxx.lsp" file.
;;; (5.) The "ARCH.mnc" loads the "ARCH.mnl" file automatically which contains many
;;; misc functions required to operate this program.
;;; (6.) The "ARCH_SUBROUTINES.fas" contains all of the subfunctions.
;;; (7.) All bitmaps for the toolbars are compiled in the "ARCH.dll" which is loaded
;;; automatically.
;;; (8.) The "ARCH.dcl" file must be located in the acad support file search path
;;; it contains all of the dialog box widgets for the arch program.
;;; @include "..\\ARCH.dcl"
;;;
;;;
;;; General Rule is to NOT edit the acad200Xdoc.lsp file because it is an Autocad file
;;; that CAN and WILL be replaced if you install patches. I would suggest using the
;;; acaddoc.lsp for the code. Following is a list of AutoCAD, Express Tools, and
;;; user-defined files in the order they are loaded when you first start the program.
;;;
;;; File For use by:
;;; acad200X.lsp AutoCAD
;;; acad.rx User
;;; acad.lsp User
;;; acad200Xdoc.lsp AutoCAD
;;; acetutil.fas Express Tools
;;; acaddoc.lsp User
;;; mymenu.mnc User
;;; mymenu.mnl User
;;; acad.mnc AutoCAD
;;; acad.mnl AutoCAD
;;; acetmain.mnc Express Tools
;;; acetmain.mnl Express Tools
;;; s::startup User
;;;
;;; To make sure you are pulling the correct acaddoc.lsp copy and paste the following
;;; line to the command line (findfile "acaddoc.lsp") You should get the path returned
;;; and if it is not where you think the file is installed you have more than one file.
