*error* function bad argument type: stringp nil - from Pull-down menu macro

[csiress]

I have created a pull down menu with this line in it.

ID_CAS2 LISP [HATCH FIX]^C^C(setenv "MaxHatch" "1000000")

However, this error occurs: error: An error has occurred inside the
*error* functionbad argument type: stringp nil

I am pretty certain that it's the quotation marks around MaxHatch and 1000000.

How do I fix this? I really don't want to type (setenv "MaxHatch" "1000000") in the command prompt.

Thank you for your help.

Hi Craig

Please note I have *moved* this thread from the AutoCAD Tips & Tricks forum to this one, as I feel this particular forum is a more appropriate place for such a topic.

Thanks, Mike

Hi

Works for me.

I Copied and Pasted...

ID_CAS2 LISP [HATCH FIX]^C^C(setenv "MaxHatch" "1000000")

into a Custom menu file.

Reloaded the Custom menu file.

Clicked "HATCH FIX" from the Custom menu pull-down area.

Environment variable MaxHatch was correctly set to 1000000 ( without any errors reported ).

Is it possible to post an example menu file ( as an attachment ), that demonstrates the behaviour you see at your end...

Have a good one, Mike

The error you quoted *error* functionbad argument type: stringp nil occurs because nil was passed to a lisp function expecting a string. It has nothing to do with your menu macro.

When does this error occur? When the menu is loaded? Check the MNL file.
If your menu is "custom.mnl", inspect "custom.mnl" for a lisp coding error.

Thank you for your help. I had placed the string in the MNS and that was causing the error. I placed the string in the MNU and reloaded and it worked without any issues.

Again thank you.

I get something very similar but it happens every time I load CAD. This is what I get:
; error: bad argument type: stringp nil
It doesn't seem to cause any issues but it shows every time I load.

Kevin, when it displays at startup, it means there is a problem routine or function within one of your autolisp startup files.

OK Opie here is the list of commands prior to the error:

OK Opie here is the list of commands prior to the error:

We cannot diagnose with just that info.
Look at your startup LSP files, such as "acad.lsp", "acaddoc.lsp", "*.mnl" (where * is the name of any menu loaded), etc. Remove them from being loaded one at a time, until the problem goes away.
