Hi,
I am trying to modify a FILE1 through JCL which is created say in setp01.
In step02 I want to change first two line of that FILE1 with two specific lines. I don't want to do it manually since this needs to be done for 11 files. Also I don't want to write any COBOL code.
But, really not sure if this can be done using JCL. Any help will be great. |

No, because JCL merely informs the CPU which program to process and which files to use.
So you will need to write some sort of code at some stage
SAS, REXX, ISPF Edit, SORT, COBOL, PL/1 ......... whatever |

| You need to tell us EXACTLY what it is that you want to do to get any useful assistance. |

I have one control card
In that file the first two lines are
| Code: |
LOAD DATA LOG NO INDDN SYSREC00 INTO TABLE
XXX.TABLE |
I want to modify this with
| Code: |
LOAD DATA INDDN SYSREC REPLACE LOG NO NOCOPYPEND
INTO TABLE XXX.TABLE |
This control card is getting generated in step1. And I am using it in step2. But before using I want to do the above modification. |

IFTHEN=(WHEN=NONE,BUILD=(C'INTO TABLE',5,63))

| Why not just generate the card correctly in STEP1 |

| You mean correcting STEP1? It is the best option. |

| No. I did what Bill suggested. Because correcting Step1 is not possible as it is getting generated automaticcaly while I am taking unload of table. |

Another problem I am facing.
I used the below card
| Code: |
IFTHEN=(WHEN=(7,4,CH,EQ,C'WLTC'),
OVERLAY=(C'EFGH ')) |
Input:
I expected
But it is coming as
Someone please put some light on it |

Try this.
| Code: |
IFTHEN=(WHEN=(7,4,CH,EQ,C'WLTC'),
BUILD=(1,6,C'EFGH',11,10)) |
YOu cam make use of FINDREP also for this requirement |

Priyanka,
If you don't specify a Column in OVERLAY, the default is "1". There is no "where I want it to go, could be different each time" default.
| Code: |
IFTHEN=(WHEN=(7,4,CH,EQ,C'WLTC'),
OVERLAY=(7:C'EFGH')) |

Chandan,
BUILD will always generate a new version of a record. OVERLAY won't unless the record is extended. BUILD always has to specify fields for all the data and the thing being changed. OVERLAY only the things being changed, so less open to typos and other assorted mistakes.
Why would you use FINDREP for that? |

Bill,
Apologies..my posy bit unclear..
I meant to say if Priyanka doesn't want to make use of IFTHEN BUILD,she can make use of FINDREP also..
Thanks for explanation on Build and overlay..
Will keep in mind that if we are not going to extend the record its better to use overlay
Regards,
Chandan |

Ok, but FINDREP is FIND and REPlace. IFTHEN=(WHEN=(logexp is "it's here, I don't need to go searching for it" (if not using SS as a fieldtype).
It will make the code less clear (and slower) to use FINDREP where IFTHEN is much more obvious. |

Thank you all. Overlay worked for me. I think we can use the following as well.
| Code: |
| INREC OVERLAY=(5:5,5,CHANGE=(5,C'12345',C'ABCDE'),NOMATCH=(5,5)) |

Yes, CHANGE would be possible. However, again I think it loses clarity as CHANGE would usually be fore more than one transformation.
CHANGE doesn't get used nearly enough, so good work in getting to it. |
