Re: Retrieving a Pointer to an Object

Bill,

I have not tried all pointers types, but you can pass a system pointer as a 
procedure pointer.  I would guess you could also pass them as space pointers.  
I have done this to return a pointer to a service program.  I don't know of an 
easy way to get the internal type, but if you do a dmpobj of any object it 
shows the internal type on the dump.  I can send the MI source if you need it, 
I hesitate to post it because I am not sure the authority structure I am using 
for the RSLVSP is correct, and I don't have a functional concepts manual.

Following is the prototype I use to get service program pointers from an MI 
program.

     DGetSrvPgmPtr     PR                  EXTPGM('SYSPTR')
     D PR_SrvPgm                     10A                                        
Program name.
     D PR_SrvPgmPtr                    *   PROCPTR                              
Pointer to pgm.

I want to be able to obtain a pointer to an object. (Specifically, I am tearing 
apart
QRYDFN's.  Yes, I have seen and used the MI RTVQRYF, but I would like to put 
the bulk
of the logic in the RPG program since I don't know MI well enough).

I know I have the MI written correctly to get the system pointer, but I don't 
know
how to pass it back to the calling RPG program so it can use it.  Could someone
possibly point me to an example?  Also, is there a table anywhere that shows the
translation between object type and the machine object identifier?  I know a 
library
is x'0401' and a query definition is x'1911', but I would like to know it all.

Your help is appreciated.

Bill
