Reply with quote

Hi Everyone,

1. I am using Xped/TSO, and I need to setup the Xped environment. I need some help regarding setting up the environment for batch programs.
2. DDIO files. I am not getting the information regarding the file format and the explanation for the first two steps (specially DSN whether it is a PS/PDS/VSAM cluster/anything else) in the following JCL:

//XOPTIONS DD DISP=SHR,DSN=XT.XT64B1.XOPTIONS
//CWPDDIO DD DISP=SHR,DSN=FLGFGR1.COBOL.DDIO
//CWPPRMO DD *
COBOL(OUTPUT(PRINT,DDIO))
PROCESSOR(OUTPUT(NOPRINT,NODDIO),TEXT(NONE))
LANGUAGE(VSCOBOL)
DDIO(OUTPUT(NOLIST,NOXREF,FIND,NODMAP,NOOFFSET,COMPRESS))

if you have xpeditor/tso in your environment,
go to the utilities screen 3.something (in xpeditor).
the purpose of one of the screens is to establish a DDIO file.
PF1 (online help) is rather good with the explanation.

the control cards that you have shown are for your compile jcl.

1. Consult your site support group. The specifics on how to do this are set up differently for each site and nothing we tell you may work on your site.
2. DDIO file format is none of your concern. Compuware provides utilities to define, initialize, and maintain DDIO files. Your site support group handles them and must do so as there are interrelationships with other files (such as shared directories) that mean applications people should not be setting up their own DDIO files. Further, setting up your own DDIO file is not a good idea if you're wanting to use it in a CICS region as that filie needs to be established in the region by your site support group.

Thanks guys, but I get to know that the DDIO files are nothing else then VSAM RRDS clusters, that will be storing the information corresponding to the compiled module. One DDIO file can store control information for Multiple Modules.

Hello,

Is there a question here?

Is this now working on your system?

This is bit late but I believe I do not interrupt much...

DDIO files do not have to be VSAM; they can also be sequential. When VSAM they are ESDS.
