/RANT ON
Once more let us clarify exactly what JCL is.
it is Job Control Language.
By itself it does nothing. It is used to invoke the chosen program and to define which datasets are to be used by the DD names associated with the chosen program.
JCL does not have magical powers that solve all problems, JCL is merely the vehicule for telling the processor which program you want it to execute.
/RANT OFF
So maybe if you would care to elaborate on exactly which program you wish to execute, then I'm sure some help will be found. |

| As you have stated your question, it cannot be done. JCL does not have any date symbolic symbols so you cannot tell Sunday from Wednesday. |

Often people decide on some solution(Which can not be actually solution) for some problem and then ask how to achieve that solution.
Rather they should state the problem here. May be people here can give better\ correct\ efficient solutions and the way to achieve that too... |

| I need to agree with Robert and expat. However, tell us how do you identify files was created on some particular day - do you populate some date-field in the file itself? |

| Sambhaji, a significant percentage of the postings on this forum are from people who have decided how they're going to solve their problem and want help implementing their chosen solution (whether or not that solution makes sense, is efficient, or even can be done at all). They're usually the ones arguing that they "have" to use X method. While it would be nice if they started posting the problem instead of the problems they're having implementing their solution, I suspect that's not likely to change anytime soon. |

The data set label; I can think of a couple-three ways to read it off the top of my head. |

the best way would be to use Your scheduler variable substitution facility,
speak to Your support. |

I agree on this Enrico.
It is too site specific but we do have similar thing at our shop. We use CA7.
We have 7 different schedule id running for all days of week from 11 through 17
| Code: |
#JI,ID=11
//PROC0010 EXEC MYPROC,DAY=MON
#JI,ID=12
//PROC0010 EXEC MYPROC,DAY=TUE
#JI,ID=13
//PROC0010 EXEC MYPROC,DAY=WED
#JI,ID=14
//PROC0010 EXEC MYPROC,DAY=THU
#JI,ID=15
//PROC0010 EXEC MYPROC,DAY=FRI
#JI,ID=16
//PROC0010 EXEC MYPROC,DAY=SAT
#JI,ID=17
//PROC0010 EXEC MYPROC,DAY=SUN
#JEND
//*
|
Here DAY symbolic parameter gets value based on Schedule ID |

| If you're running CA-7, you can use their CARPROC to create symbolic variables including DAY (which is the day of the week). If the original post had mentioned CA-7, instead of just JCL, the issue would be resolved by now. |

Akatsukami - the way question is stated, I'd like to stay on safe side and during this year-end would not like to sound psychic to understand the question - before I could suggest something nice, I wanted to understand the question first and so the statement... 
See the responses so far, we're at CA-7 suggestion and we started from JCL...  |
