looking for help with a menu command

I'm currently working on updating our custome menu and I would like to
beable to open our drafting manual from within autocad. it's currently in
PDF format.

so here is what I want to beable to do. click on a button or select the
command from the pull-down and have adobe acrobat open our cad manual.

Is this possible and if so can someone tell me how to do it?

Thanks
Dylan

 

;here's an example with hardcoded paths
;;; you could make much better by eliminating the hard code
;;; or just substitute your paths
;;; i'm just too lazy to make it a good function cause this is all i need.

(defun CDF( / AppLocation Title DocLocation defaultLocation)
(setq AppLocation "E:\\PROGRAM FILES\\ADOBE\\ACROBAT
5.0\\READER\\ACRORD32.EXE" );set your location or do findfile or/????
(setq title "Select PDF file to Open")
(setq defaultLocation "C:\\0\\0INFO\\LISPINFO\\");set your location or
offer prompt
(setq DocLocation (Getfiled title defaultLocation "pdf" 0))
(startAPP AppLocation DocLocation)
