The if statement @ line 543 sets the toggle box for the "lay" variable on or off depending on the presence of variable "lay-p", same with other toggles, so no matter what you set them for in the dcl code, they are set in the lisp file as needed. The lisp file over-rides the dcl definition file, once the dcl is opened the lisp then populates the fields in it per the code within.
That's why I prefer to set toggles, radio buttons etc. from the lisp file not the dcl definition.
