Topic: error: bad argument type: consp nil

[mattsibum]

Hi all,

Have a routine i use to load / unload xrefs, but is displaying this error on the first run "error: bad argument type: consp nil". If i reload the lisp file, the error disappears, but want to fix it to avoid reloading every time. Lisp file attached.

Any help would be great.

I have no issues with the execution


Command: _XATTACH
Overlay Xref "201-Test02": I:\Jobs\_Dev\ST201\201-Test02.dwg
"201-Test02" loaded.
Command: XXX

Personally I'd add an error handler that includes a back-trace (BT) which will assist sorting out any issues.

In the meantime :

Also you should get in the habit of localizing your variables .. that can bite you in the arse . Welcome to the Swamp.

If i reload the lisp file, the error disappears, but want to fix it to avoid reloading every time.

That tells me it's most probably global variables being set to something else somewhere, and then the next time you run the code the needed values are wrong.



It does seem that this is the case as per ronjon's test.

Thanks for your help everyone, will try fix any global variables and see if that works.
