A run time error:
Error: Attempt to invoke function READ on arguments...
occurs when the application uses the Lisp reader but delivery has removed that functionality.
The solution is to retain the Lisp reader, by the delivery keyword :keep-lisp-reader.
If your application does not use the reader directly, the error may be due to a LispWorks function using it. Please see 10.2 Delivery and the Lisp reader for more information.
