The MNL File for an AutoLISP Menu
When AutoCAD for Mac loads a customization file, it searches for an MNL
file with a matching file name. If it finds the file, it loads the file into memory.
This function ensures that AutoCAD for Mac loads the AutoLISP functions
that are needed for proper operation of a menu.
This function ensures that AutoCAD for Mac loads the AutoLISP functions
that are needed for proper operation of a menu. For example, the default
AutoCAD for Mac customization file, acad.cuix, relies on the file acad.mnl.
This file defines numerous AutoLISP functions used by the menu. The MNL
file is loaded after the acaddoc.lsp file.
Prevent AutoLISP Errors When Loading Startup
Files
If an AutoLISP error occurs while you are loading a startup file, the remainder
of the file is ignored and is not loaded.
Files specified in a startup file that do not exist or that are not in the AutoCAD
for Mac library path generally cause errors. Therefore, you may want to use
the onfailure argument with the load function. The following example uses the
onfailure argument:
(princ (load "mydocapp1" "\nMYDOCAPP1.LSP file not
loaded."))
(princ (load "build" "\nBUILD.LSP file not loaded."))
(princ (load "counter" "\nCOUNTER.LSP file not loaded."))
(princ)
If a call to the load function is successful, it returns the value of the last
expression in the file (usually the name of the last defined function or a
message regarding the use of the function). If the call fails, it returns the value
of the onfailure argument. In the preceding example, the value returned by the
