What task exactly are you trying to accomplish? Are you writing operations automation software or do you just want to see what is running? If you are writing automation software, then COBOL is definitely not your best choice of languages since you probably need authorization and the ability to issue SVCs directly. But if all you are wanting is to find out what is running in the system, you can just chase control blokcks (CVT -> ASVT -> ASCBs etc). The control blocks are documented in the Data Areas books for MVS and there are probably several COBOL examples here and elsewhere that you can use. I know there are several Rexx execs around that run these control blocks. I just modified one of them last week for someone to find the racf id associated with each job/address space/user.
If you run your job under TSO (IKJEFTxx) and have console authority, you can use the CONSOLE command to issue commands. Trapping the output is tricky and I suspect it can only be done in assembler, but that may not be true. Output trapping is trivial in Rexx for most commands. I never tried to trap CONSOLE commands. |

Hey semigeezer, I am presently working on Automation for console and the query I have posted is not related to Automation software(AF/Operator) I am working on. Actually I just wanted to issue any operator command say (D A,L) or (D NET,ID=) or say any OPER Command on the console. I just went thru ASVT CVT and ASCB Data Areas book and found no good example or any idea about how to use it in a COBOL Code. Presently we use REXX for our Automation needs and I was just trying to explore the SVC Calls from COBOL to achieve the OPER functionality.
Would be of help if you could let me know some examples.
Thanks,
- Amit Joshi.
