svrekha, your profile lists you as a "software engineer", so I would think you'd already be familiar with sequential dataset processing.
You can't delete records from a sequential dataset. All you can do is copy all of the records you want to keep to a new dataset, skip the one you wish to delete, and create the new dataset. Then, if desired, delete or rename the current dataset and copy the contents of the new dataset into the existing dataset. Obviously, it would be beneficial for you to not write your own process, but rather use an existing utility for this.
Other than that standard process, the only other way to remove a record from a sequential dataset is by editing it. Edit it, find the record, delete the record, then save it. |

| I don't know CLIST (not too many people use it anymore) but if you describe your process in detail I might be able to hobble together some code. |

| I think you can probably use DFSORT to exclude records. That is, make a new dataset without the records that you do not like. |

Call DFSORT from your clist. (actually, rexx is preferred).
And especially, call DFSORT if you are talking about a lot of records. |
