For a fixed record length file, you can't without copying it.
A variable length file could be altered in place by changing the max record size. |

Without copying it..? Perhaps I misunderstood... |

I would suggest a trick for this.
Please copy F1 ( disp=old,del,del) to another dataset with another name F2 ( disp=new,catlg,del , lrecl=220) using the OUTREC statement OUTREC FIELDS = (1,200,20x).
Now copy the file F2 to F1 ( disp=new,catlg,del )
Hope this helps |

Excellent, and if there is a problem you also delete the original file  |

Yes that was wrong.. My logic is to copy this to a intermediate dataset using outrec command and delete the orginal file so that we can create and copy the same data we have in the intermediate file.
