RELATED IDEAS

Enable Enterprise PL/I programs which are compiled as NORENT (and linked into a NORENT/NONDLL program object/load module) to be able to fetch/call program objects which are linked as RENT/DLL, such as PL/I AMODE(64), JAVA, and other modern APIs.

Use case:

Enterprise PL/I has the following requirements/restrictions documented in Chapter 1 of the Programming Guide (GI13-5620-00) regarding the RENT compiler option:

 

“RENT (compiler option)

If you link a module (either MAIN or FETCHABLE) containing one or more programs compiled with the RENT option, you must specify DYNAM=DLL and REUS=RENT on the link step.

:

:

Code compiled with NORENT code cannot fetch a module containing any code compiled with RENT.”

 

With current RENT compiler option requirements/restrictions the only way for a NORENT application to be able to fetch/call a RENT/DLL is for the caller to be recompiled as RENT and relinked as a RENT/DLL.  And there is a ripple effect if the routine that is fetching/calling the DLL happens to be a fetchable program it’s caller must also be recompiled as RENT and relinked as a RENT/DLL…..and this process is required all the way back to, and including,the main application.

 

 

Business justification:

The current RENT compiler option requirements/restrictions effectively prevent NORENT PL/I legacy applications from using modern RENT/DLLs.  If this RFE were delivered it would enable NORENT PL/I legacy applications to be modernized with the capability to call DLL code such as PL/I AMODE(64), JAVA and other modern APIs.
