Someone named Bill Woodger posted to the Google Groups mirror of this list the following link that gives several reasons why COBOL V5 requires PO executables and therefore PDSE or Unix directories:
http://www-01.ibm.com/support/docview.wss?uid=swg27041176 >From that link (which is for a white paper on V5 and PDSE's), which Mr. >Woodger also quoted in a later reply only in Google Groups and which Don >Poitras re-quoted in his reply on this list: "The need for PDSE datasets and Program Objects are built into the very core of COBOL V5. Just a few examples of features that COBOL V5 uses and will use that require Program Objects(PO) and thus PDSE datasets for executables are: Improved init/term scheme relies on user-defined classes in object, requiring PO QY-con requires PO (A performance improvement for RXY (long displacement) instructions. Condition-sequential RLD support requires PO A performance improvement for bootstrap invocation PO can get page mapped 4K at a time for better performance NOLOAD class DWARF debugging data requires PO Common reentrancy model with C/C++ requires PO XPLINK requires PO and will be used for AMODE 64 " HTH Peter -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Robert A.

The real question is "What is Cobol V5 creating that needs the Program Object format?". IOW: It outputs something that needs a Program Object when bound. What is this capability that can not be done in a normal load module? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
