o/p file: same layout needed
Requirement: I/P file with a millions of records and I know the record with claim-number (pos 1-13) and need to change the date for that record and need to write to o/p file with all the records from I/p to o/p including the modified record.
Please help me.
Thanks,
Subbu. |

read about OVERLAY statement in DFSORT with an INCLUDE condition,
BTW changing claim date? I hope nothing unethical is done. :-) |

since You told nothing about the position of the <key> and the data to be changed
we can only hint on the general format of the sort statements to be used
Code: |
// ... all the usual SORT jcl statements
//SYSIN DD *
OPTION COPY
INREC IFTHEN=(WHEN=(position,lenght,format,EQ,<key data>),OVERLAY=(position:<overlay data>)) |
searching the dfsort forum with the OvERLAY keyword will give You zillions of examples |

Might be a good idea to have a copy of the originals on a seperate tile. |
