Hi,
I have a question about JCL continuation.
If it's possible to continue following ".TEST" part from next line, since which already exceeded "Position 72". 
=COLS> ----+----1----+----2----+----3----+----4----+----5----+----6----+----7--
000034 //JS010D EXEC PGM=IEFBR14 ** DELETE **
000035 //*
000036 //DD1 DD DISP=(MOD,DELETE,DELETE),
000037 // SPACE=(10796,4),
000038 // DSN=&FIRST.&LEVEL1..&SECOND.&LEVEL2..&THIRD.&LEVEL3..&FOURTH.&LEVEL4.TEST
Thanks  |

Why dont you requce the symbolic parameter lenght? Like LEVEL1 to L1 etc.... |

Hi Murali,
I just make this as an example, just suppose the symbolic parameter length is too long for the DSN name. Because some time the symbolic name is fixed for business issue. 
Thanks

This is a reasonably simple thing to test out on your own. In fact it would probably have been faster for you to do so.
Dare I ask if this is a HOMEWORK question. |

Hi Expat,
I have tried a lot, but failed. I even doubt if it's allowed in JCL.
Unfortunately, it's not a HOMEWORK...

Hello Ban,
While this meets a business processing requirement, there is possibly not a business requirement for the long symbolic parameters. I'd suggest meeting the business need with shorter symbolic parameter names. |

Hi Dick,
Actually, this is just a Example.
Yes, the real lenght of single symbolic parameter is not so long, but the total length of ALL the parameters is really exceed 72.
So, is there any other way can solve this problem except the way to shorter the symbolic parameters? Or, it's impossible in JCL?
Thanks,
Ban |

| Wouldn't this violate the allowable length (44 charcter) of a qualified DSN as well, if it crosses the 72 column? |

No.
| Code: |
----+----1----+----2----+----3----+----4----+----5----+----6----+----7--
// SET SYM1=A,SYM2=B,SYM3=C
//STEP1 EXEC PGM=XYZ
//DDDD DD DSN=&SYM1.&SYM2.&SYM3..&SYM1.&SYM2.&SYM3..&SYM1.&SYM2.&SYM3, |
Though your DSN name (in parms) is 60 and odd.... your actual datasetname is going to be 10+ in length. |

Hi,
I thought to locate a DSN such as
| Code: |
| RACFID.A.B.C.D.E.F.G.H.I.J.K.l.m.n.o.p.q.r.s.t |
I thought to increase the number of delimiters ("." in this case) while shorting the length of symbolic parameters; A,B..etc in the final DSN would be "sandwiched" via symbolic parameters. That's why my previous post comes in..I didn't think in right way.. ...I (again) think.
Well, for the original thread, then, length of the symbolic parameters should be shorten, as suggested ealier. |

Anuj,
Not at all. As long as you are open for learning new things and SHARING your knowledge with others. |

Hi Luban
If you are writting and DSN name is reaching upto 72 columns then just write it in next line. JCL will automatically take it as continuation.
a non-space in position 72 indicates a continuation
Please correct me if I am wrong.... |

Hi Guys,
Thanks for your help.
It looks like that shorten the symbolic parm is my only choice 
Just wish won't meet such kind of DSN again
Thank you all again.

One other possible solution, do your substitution in multiple steps, ie. use intermediate variables to hold parts of the final dsn.
| Code: |
2 // SET FIRST=A
3 // SET LEVEL1=B
4 // SET SECOND=C
5 // SET LEVEL2=D
6 // SET THIRD=E
7 // SET LEVEL3=F
8 // SET FOURTH=G
9 // SET TEST=H
//**********************************************************
10 // SET DSNP1=&FIRST..&LEVEL1..&SECOND..&LEVEL2.
IEFC653I SUBSTITUTION JCL - DSNP1=A.B.C.D
11 // SET DSNP2=&THIRD..&LEVEL3..&FOURTH.&TEST
//**********************************************************
IEFC653I SUBSTITUTION JCL - DSNP2=E.F.GH
12 //JS010D EXEC PGM=IEFBR14
//*
13 //DD1 DD DISP=SHR,DSN=&DSNP1..&DSNP2
IEFC653I SUBSTITUTION JCL - DISP=SHR,DSN=A.B.C.D.E.F.GH |
I hope this helps. |
