Let me start out by saying I am a Rexx guy. I use it for many things.
But loading data into a DB2 table from a sequential file, would be way down on my list of practical uses.
Why not use a DB2 utility? Much more efficient and easy to write cards for.
Next, I need a new car. If any One help me, please let me know.
We have the same chance at getting help asking this way.
If you give some specifics, perhaps some help is possible, but right now, not so much. |

Hareesh,
Your problem statement is fairly wide open. May I please request you to provide more details on selecting this approach. Is there any further restrictions which forced you to select rexx when this can be done with simple jcl. |

| Actually I am not Allowed to use Load Utility. Writing a Cobol Program Means Too Many Components(PROG,PROC,PLAN) etc which can be completed with a single Parm using REXX. |

Can you please let me know what you are thinking here. May be I am too new to Mainframe, but if not load utility, then how do you expect rexx to load into table? Do you want Insert statements?

We are not advising this. We are suggesting load utility which can be executed directly using JCL. |

Why not read up in the SQL manual about how to write DB2/Rexx programs?
Yes, the required information is there - an entire chapter. I know because that is what I did. |

How familiar are you with Rexx?
The Rexx/DB2 interface is not the best. It is not as easy to work with as you think.
Your profile says you are a beginner.
I have 30 years experience with Rexx, Cobol, DB2, JCL etc...
I would not choose Rexx to do this. I would choose a DB2 utility first, then Cobol next.
You come to this forum for advice, and now you have it.
The person who said you can not use a utility should first be fired, then shot.

Rather than shot then fired. Easier to drag them out the door that way. |

My first choice would be the DB2 LOAD utility. So would my second and third choices. Inserting data via DSNREXX calls is very inefficient and would be a poor choice for more than a handful of rows.
If you must use Rexx, another approach is to read your input file and format SQL INSERT statements that you can run in a subsequent step via DSNTEP2. Even this approach is not optimal; you can do the same thing with relatively little effort (and much more efficiently) using DFSORT to format the INSERT statements. |

I note that you have not said why you are not allowed to use the LOAD utility. If there is a sound reason, then we may be able to assist you in a way that does not involve writing a Rexx exec (which Messrs. Leahy and Porcelan have told to you to avoid). If it's an arbitrary "It's the requirement!", then I recommend that you push back. |

IMO topics which develop like this one,
- requirements/ solutions against any good judgement and good practices-
should be locked after a while.
that what I will probably do shortly.
no reason to waste time on moronic requirements |

So what? Develop the components. I don't think it will take more than 30 minutes. |

I once wrote a small CICS inquiry system, made up of five PL/I programs and two BMS maps, before my coffee break. ;) |

May be he meant to save work-site compensation claims as well 
Anyways, unless the user gives us a reason to follow this approach, we all should just wait to hear back for a while (just a suggestion) |
