Command Autoloader

When you automatically load a command using the load or command functions,

the command's definition takes up memory whether or not you actually use

the command. 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).
