A PDSE Program Object allows to use of DLL linkage (DLL Cobol Compiles) context instead of standard, without special handling during the link edit steps.
It also supports OOCobol operation modes natively. A DLL mode program object is always dynamically linked, however it allows one to function package many small callable functions into one program, but reference the functions by name from the calling program. (this is done via the DDL Export on the subprogram, and DLL Import during the Main program) It is a very handy way to keep small called routines easily findable, and maintainable, as they are all in one program, instead of having a program for each one. The callable function names can also be 32 characters long. I've tested using the DLL Linkage mode, and it works great. However we are not planning to use it until we have a new application design project. We are not changing our existing applications to it. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Jeffrey Deaver Sent: Thursday, June 07, 2007 7:31 AM To: [email protected] Subject: PDSe Program Objects vs PDS Load Modules OK. So I've recently been introduced to the fact that when you copy a load module from a PDS to a PDSe with IEBCOPY, it magically becomes a Project Object. I've been reading what I can find and it seems that operation is ok, but that moving the other way... PDSe PO to a PDS LM is a no no since their may be 'features used in the Project Object which are not available to the Load Module'. I then read, however, that the same binder creates the PO or LM based on the library its headed to. Huh? So my questions are this: 1) Did I get that right? 2) Where is the document that describes the features available to Project Objects which are not available to Load Modules? I've got a developer group that recently 'discovered' that their test libraries are PDSes and their production libraries are PDSs. They saw the difference in the look of the load modules and got to asking questions. They have had no trouble with this operation - just curious at this point. Thanks!
