Hi,
The IDCAMS utility will help me to know if any dataset exists or not.
In my JCL a PROC is called and infile is provided as override.
//ABC PROC=ABC,INFILE=AAA.BBB
Using this symbolic parameter it is possible to check if it file exists or not in PROC:
//JS10 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
LISTCAT ENTRIES(&INFILE)
/*
While using above syntax i am getting following error:
IDCAMS SYSTEM SERVICES TIME: 07:48:
LISTCAT ENTRIES(&INFILE)
IDC3203I ITEM '&INFILE' DOES NOT ADHERE TO RESTRICTIONS
IDC3202I ABOVE TEXT BYPASSED UNTIL NEXT COMMAND. CONDITION CODE IS 12
IDC0002I IDCAMS PROCESSING COMPLETE. MAXIMUM CONDITION CODE WAS 12
Regards,
Krunal Bafna |

Unless you are using z/OS 1.13, IDCAMS will not allow ANY use of symbolic parameters (anything starting &) so what you are attempting will not work, period, until your site upgrades to z/OS 1.13.
Once submitted and through the JES converter / interpreter, it is not possible to change JCL -- so I suspect you will need two jobs to do whatever you are attempting to accomplish. |

Trying to replicate your test, and I can't get far enough along to even invoke the IDCAMS step without getting a JCL error. Granted, I'm not on the latest version of z/OS.
Could you post your JESYSMSG output that shows how JES is handling the variable substitution of &INFILE from the job, to the PROC, and ultimately to that step? |

OK, this is related to this topic. Perhaps I should have said "next time".
If you put your file on a DD name and submit the Job, the system will go out of its way to tell you that the file does not exist, if it doesn't.
What you have not explained is why you otherwise want to know whether the file exists. If you explain the reason you are trying to do it this way, you may get some answers.
If you are desperate to use IDCAMS in this way, and unwilling to explain further, then you need to generate the IDCAMS control card from a program which can take the substituted symbol. DFSORT comes to mind, for one. |

I am trying to do this beacuse:
I am submitting the JOB online using CICS. The first step I need to check if user has entered valid dataset or not. If dataset does not exists, it shall be an invalid testing. So i need to check if file entered exists or not.
SO i am using LISTCAT as first step in my proc to check validity of file. |

so, you are going to a lot of trouble to determine if a dataset exists or not.

WTF does that mean?
forget this nonsense about validating ds existance.
let the job bomb on a JCL error (allocate attempts to allocate a non-existant file) |

Surely you're not letting a user type a dataset name? What if they try with something they shouldn't be accessing?
What are they going to be doing with the dataset?
Can't you give them a list of datasets (which exist) which are relevant to their task, and get them to pick something from the list? |

I am Z/OS 2.1 and I don't see any references to IDCAMS allowing symbolic substitution in its SYSIN contents i.e.LISTCAT ENTRIES(&INFILE) as posted by Mr. Sample at Posted: Mon Mar 19, 2012 8:03 am
I need to know if a dataset exists, and if it doesn't, then allocate it. I want to pass a portion of the dataset name to IDCAMS to be substituted.
ALLOCATE DATASET('someprefix.&ACCUM'),OLD
RC=12 when the dataset does not exist, and 0 when it does.
Can someone suggest a way to pass the value of &ACCUM as a parameter or build it using JCL |

This JCL works just fine on my z/OS 2.1 system:
| Code: |
// EXPORT SYMLIST=(INFILE)
// SET INFILE=RLS.JCL.CNTL
//STEP1 EXEC PGM=IDCAMS,REGION=0M
//SYSPRINT DD SYSOUT=*
//SYSOUT DD SYSOUT=*
//SYSIN DD *,SYMBOLS=EXECSYS
LISTCAT ENT(&INFILE)
/*
// |
and output is
| Code: |
********************************* TOP OF DATA *********************************************************************
IDCAMS SYSTEM SERVICES TIME: 16:45:55 07/12/16 PAGE 1
LISTCAT ENT(RLS.JCL.CNTL)
NONVSAM ------- RLS.JCL.CNTL
IN-CAT --- CATALOG.VMVS001.MASTER
IDCAMS SYSTEM SERVICES TIME: 16:45:55 07/12/16 PAGE 2
THE NUMBER OF ENTRIES PROCESSED WAS:
AIX -------------------0 |
There is a chapter in the JCL Reference manual on Using symbols in JES in-stream data that is a starting place. If you were looking at the IDCAMS documentation, you were looking in the wrong place. This is a change to z/OS JCL and JES, not IDCAMS. |

not an IDCAMS facility/feature,
symbolic substitution in inline data is a a system facility/feature |
