In a jcl i mentioned both temporay dataset and symbolic parameter.
Ex:
dsn=&&WORK
and in an another jcl statement dsn=&WORK
Then &WORK is teated as temporay dataset or symbolic parameter? |

| It is a temporary dataset in both cases. |

Hi Superk,
I suppose It will not treat as a temporary dataset in both the cases.
&&work alone is treated as a temporary dataset and &work will be treated as a symbolic parameter.
Can u please recheck it again and correct me if iam wrong.
Thanks,
Anu |

I stand by my original response.
As a matter of fact, both names (DSN=&&WORK and DSN=&WORK) will create the same temporary dataset name.
If you have test results that show a different result, please post them. |

Here is my proof:
| Code: |
//STEP0001 EXEC PGM=IEFBR14
//FILE1 DD DSN=&SYSUID..WORK.DATA,DISP=(MOD,DELETE,DELETE),
// UNIT=SYSDA,SPACE=(CYL,(1,0),RLSE)
//*
//STEP0002 EXEC PGM=ICEGENER
//SYSUT1 DD DATA
THIS IS THE RECORD FOR &&WORK
/*
//SYSUT2 DD DSN=&&WORK,DISP=(NEW,PASS),UNIT=SYSDA,
// SPACE=(CYL,(1,1,),RLSE)
//SYSPRINT DD SYSOUT=*
//SYSIN DD DUMMY
//*
//STEP0003 EXEC PGM=ICEGENER
//SYSUT1 DD DSN=&&WORK,DISP=(OLD,DELETE)
//SYSUT2 DD DSN=&SYSUID..WORK.DATA,DISP=(,CATLG,DELETE),
// UNIT=SYSDA,SPACE=(CYL,(1,1),RLSE)
//SYSPRINT DD SYSOUT=*
//SYSIN DD DUMMY
//*
//STEP0004 EXEC PGM=ICEGENER
//SYSUT1 DD DATA
THIS IS THE RECORD FOR &WORK
/*
//SYSUT2 DD DSN=&WORK,DISP=(NEW,PASS),UNIT=SYSDA,
// SPACE=(CYL,(1,1,),RLSE)
//SYSPRINT DD SYSOUT=*
//SYSIN DD DUMMY
//*
//STEP0005 EXEC PGM=ICEGENER
//SYSUT1 DD DSN=&WORK,DISP=(OLD,DELETE)
//SYSUT2 DD DSN=&SYSUID..WORK.DATA,DISP=(MOD,CATLG,DELETE),
// UNIT=SYSDA,SPACE=(CYL,(1,1),RLSE)
//SYSPRINT DD SYSOUT=*
//SYSIN DD DUMMY
//*
|
which results in this output data:
| Code: |
****** ***************************** Top of Data *********
=COLS> ----+----1----+----2----+----3----+----4----+----5-
000001 THIS IS THE RECORD FOR &&WORK
000002 THIS IS THE RECORD FOR &WORK

Hi Kevin,
If you make steps 4&5 a PROC (proca) and execute it thusly:
// exec proca,work=abc
work becomes a symbolic. |

Hi Kevin,
One more doubt. But please take this in a positive sense. I am not arguing with you.
Have you used Set statement?????
If we are not giving any // SET WORK='MSDV' kind of statement then what you said is right.
Even i tried the same example given by you by keeping the set verb in the JCL.Hope you got my point. |
