LISP Routines Give Errors in New Drawings

[bradl]

I have a couple of LISP routines that will error out when I try to use them in the second or later drawing for an AutoCAD session. These programs have been used for many years, and I have only noticed this since AutoCAD 2022 & 2023. However I did go back and reinstall 2021 and I still have the same issue. This has been a problem since my system was upgraded last year and I started with a fresh install of AutoCAD 2022. Other installations in the office of 2022 & 2023 work as they should.

When I first open AutoCAD and load an existing drawing or start a new drawing, the list routine runs perfectly. When I open another drawing or start a new drawing; the program errors out. I can still go back into the first drawing and use the LISP routine in that drawing, but it never works in drawings opened later. If I save that first drawing and try to re-open it later it will not work unless it is the first drawing of a new AutoCAD session.

Any help is greatly appreciated

How is the AutoLISP file loaded? What is the actual error returned?

[bradl]

The file is loaded through a tool palette then starts the process.

This is the run sequence and error

Command: (if (not C:FUNCTIONS_PICK)(load"FUNCTIONS_PICK"))
C:FUNCTION-PP
Command: FUNCTION-PP
Pick first point: _endp of
Pick second point: _endp of ; error: no function definition: SEC

The actual line of code that is erroring when I stop the code line by line is
(setq SCT (SEC AR))

Where AR is the angle in radians

There is an option to load acad.lsp in every drawing.
Set system variable ACADLSPASDOC to 1.

It may be that the load expression is in the acad.lsp.

Your dependent SEC sub-function call errors, because it hasn't been loaded; you need to find that .LSP file, and load it prior to loading & invoking C:FUNCTION-PP.

I'd recommend you keep ACADLSPASDOC == 0 (to load Acad.lsp once per session), and instead use the proper AcadDoc.lsp user code file to [auto-?]load any/all needed code each time a drawing opens.

Cheers

Peter, the ACADLSPASDOC system variable change has resolved the many issues I was having, with more programs than I realized since they are rarely used.

BlackBox, it is becoming more apparent that our older programing did not use current/better methods. My goal when doing a fresh install of 2022 was to resolve some issues that kept migrating from past versions. Looks like I missed a bunch of stuff that is not used frequently.

Thank you both for your help!
