API Question

When working with APIs that have an API Error Data structure as part of the 
return, how do I define it.  I am attempting to work with APIs but keep getting 
a error:
                         Additional Message Information

 Message . . . . :   Error addressing API Parameter.                            
 Cause . . . . . :   An error occurred addressing parameter 8 of the            
   QteRetrieveModuleViews API. The reason code was 2.  The following are the    
   reasons why this message is issued.                                          
     1 -- A pointer was used that is not available for use while running in the 
   current program state.                                                       
     2 -- A pointer was used which did not point to storage that could be       
   addressed for the parameter.  The pointer may be null or may point to        
   storage that does not exist.

   (SC41-8223) for a discussion of using the source debug programming           
   interfaces.                                                                  
                                                                        More...

 F21=Select assistance level                                                    
                                                                                

So from the depth of desperation hell, I ask you for help: How do I define the 
parameter in the prototype so that I won't get this error.  I have tried a few 
things and nothing seems to work.


For example:

   D xAPIErr                      likeds(APIERR)

and
   D xAPIErr                    *

But nothing seems to work. 

What am I doing wrong?
