■ S::STARTUP Function: Postinitialization Execution on page 442
AutoCAD loads the contents of three user-definable files automatically: acad.lsp,
acaddoc.lsp, and the MNL file that accompanies your current customization
file.
By default, the acad.lsp file is loaded only once, when AutoCAD starts, whereas
acaddoc.lsp is loaded with each individual document (or drawing). This lets
you associate the loading of the acad.lsp file with application startup, and the
acaddoc.lsp file with document (or drawing) startup. The default method for
loading these startup files can be modified by changing the setting of the
ACADLSPASDOC system variable.
If one of these files defines a function of the special type S::STARTUP, this
routine runs immediately after the drawing is fully initialized. The S::STARTUP
function is described in S::STARTUP Function: Postinitialization Execution on
page 442. As an alternative, the APPLOAD command provides a Startup Suite
option that loads the specified applications without the need to edit any files.
The acad.lsp and acaddoc.lsp startup files are not provided with AutoCAD. It
is up to the user to create and maintain these files.
Command Autoloader
When you load an AutoLISP file, the command definitions in the file take up
memory whether or not you actually use the commands. The AutoLISP
autoload function makes a command available without loading the entire
routine into memory. Adding the following code to your acaddoc.lsp file
automatically loads the commands CMD1, CMD2, and CMD3 from the cmds.lsp
file and the NEWCMD command from the newcmd.lsp file.
(autoload "CMDS" '("CMD1" "CMD2" "CMD3"))
(autoload "NEWCMD" '("NEWCMD"))
The first time you enter an automatically loaded command at the command
prompt, AutoLISP loads the entire command definition from the associated
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).
