Command call for lisp

I can't seem to figure out what the command is for calling this routine. Can someone look at it and let me know please. TIA.

(defun EastNorthToXY (p / AeccApp AeccDocs AeccDoc AeccUtil)
   (if (not *acad*)(setq *acad* (vlax-get-acad-object)))
   (if
      (and
         (setq AeccApp (vl-catch-all-apply 'vla-getinterfaceobject (list *acad* "aecc.application")))
         (not (vl-catch-all-error-p AeccApp))
         (setq AeccDocs (vl-catch-all-apply 'vlax-get (list AeccApp "Documents")))
         (not (vl-catch-all-error-p AeccDocs))
         (setq AeccDoc (vla-item AeccDocs 0))
         (setq AeccUtil (vl-catch-all-apply 'vlax-get (list AeccDoc "Utility")))
         (not (vl-catch-all-error-p AeccUtil))
         (vlax-method-applicable-p AeccUtil "EastNorthToXy")
     &nbsp
      (vlax-invoke AeccUtil "EastNorthToXy" p)
  &nbsp
)

 

(eastnorthtoxy p1)
.... where p1 is the point to be processed.

Can someone look at it and let me know please. TIA.

 

What I mean is, most lisp have a command defined. Such as "defun C: xyz".
This I can not figure becaue that is not in the code and I don't see how
else to call upon the commands for the functions within the lisp. Is that
much clearer to hopefully get some help? Thanks.

 

Anyone know thr answer to this one? Would be greatly appreciated. Thanks.

 

What I posted *IS* the answer. You call a non-"C:" function by placing the
function, plus any required parameters within a set of parentheses, just
like any other LISP function. So, to call the function EastNorthToXY, with
its required parameter, the correct syntax is

(eastnorthtoxy p1) ... where p1 is the required parameter -- in this case a
point.

That's the only answer possible. If you need more information, I'd suggest
perhaps the Customization Guide section of the HELP system might be of
interest.

Revise the defun to have a c:xyz, remove the parameter 'p', and add a (setq
p (getpoint)) or other means of assigning the point. Not knowing the purpose
of the function more than (vlax-invoke AeccUtil "EastNorthToXy" p) makes
things difficult.

 

That makes more sense Dan. Guess some folks assume that everyone knows
exactly the same stuff. That is why I reitterated the question. Not that
Paul's answer would be suitable to the die hard programmer. Thanks all.
Think I will scrap this though because it doesn't even seem like it would be
of much use without a hassle. And besides, LDD has a function to do this
already.
