file. AutoLISP also provides the autoarxload function for ObjectARX
applications. See autoload and autoarxload in the AutoLISP Reference.
NOTE
Like-named AutoLISP startup files are loaded based on their Modified time
stamp; the LSP file with the most recent time stamp is loaded unless you
specify the full file name (including the file name extension).

The ACAD.LSP File
You can create an acad.lsp file if you regularly use specific AutoLISP routines.
When you start AutoCAD, it searches the support file search path for an acad.lsp
file. If an acad.lsp file is found, it is loaded into memory.
The acad.lsp file is loaded at each drawing session startup when AutoCAD is
launched. Because the acad.lsp file is intended to be used for application-specific
startup routines, all functions and variables defined in an acad.lsp file are only
available in the first drawing. You will probably want to move routines that
should be available in all documents from your acad.lsp file into the acaddoc.lsp
file.
The recommended functionality of acad.lsp and acaddoc.lsp can be overridden
with the ACADLSPASDOC system variable. If the ACADLSPASDOC system
variable is set to 0 (the default setting), the acad.lsp file is loaded just once:
upon application startup. If ACADLSPASDOC is set to 1, the acad.lsp file is
reloaded with each new drawing.
The acad.lsp file can contain AutoLISP code for one or more routines, or just
a series of load function calls. The latter method is preferable, because
modification is easier. If you save the following code as an acad.lsp file, the
files mysessionapp1.lsp, databasesynch.lsp, and drawingmanager.lsp are loaded
every time you start AutoCAD.
(load "mysessionapp1")
(load "databasesynch")
(load "drawingmanager")
