RE: Calling a RPG module from a CLLE

You need to all *CL to the ExtProc keyword on the prototype for your
Validate_Company subprocedure.
 D Validate_Company...
 D                   PR                extproc('VALIDATE_COMPANY' : *CL)
 D      xCompany                  2p 0 value

Subject: Calling a RPG module from a CLLE

I am having a problem with using an RPG module from a CLLE.

Here is the RPG module
  *--------------------------------------------------------------------------
 d Validate_Company...                                                       
 d                 pi              n                                         
 d      xCompany                  2p 0 value                                 
  *--------------------------------------------------------------------------
 d    Record_ID    s                   like(strcid) inz('CPY')               
 d    ind          s               n                                         
  *--------------------------------------------------------------------------
  /free                                                                      
       open ahpsstp;                                                         
       chain (Record_ID:xCompany) ahpsstp;                                   
       ind = not %found(ahpsstp);                                            
       close ahpsstp;                                                        
       return ind;                                                           
  /end-free                                                                  
  *--------------------------------------------------------------------------
 p Validate_Company...                                                       
 p                 e                                                         


And here is the call from the CL program.


                                                                       
            CALLPRC    PRC(VALIDATE_COMPANY) PARM((&COMP *BYVAL)) +    
                         RTNVAL(&VALID)                                

And when this line executes, the module errors out on the return with MCH3601
invalid pointer. In debug mode the parameter passed is correct. But attempting
to return the result errors out.

Can anyone point out what I am doing wrong?
