i want to pick up on record, go to another flatfile and fetch all the records for that customer and write to a new file.

i want to do this till end of parmfile.

But my requirement is , i cant use any programs, i have to do this using the JCL , control cards only.

JCL is a control language, not a programmatic one. You can't read files using JCL only.

Hello,

Please explain why you can't use any programs. Is there some business reason or is this meant to be a learning experience or a test of what you know or can find out?

You can do this using sort. Sort both files in customer number order. Match the 2 files placing the records you want in a new output file.

A lot of IDCAMS might also do the job but I agree with dick: who would want to do this and why icon_rolleyes.gif

That's funny. I could swear that SORT, IDCAMS, and all of the IBM Utilities are all programs. I guess there's something new to learn everyday! icon_wink.gif

Even the machinecode we used to type at the console in the 6=xties to start the engine of the cardreader or tape-unit were tiny little programs. With machinecode we even composed music; the lighter the calculation the deeper the bass-sound, the heavier the calculation the higher the sound. Even behind this machincode there still was the operating system which at it's own also was a program.

No crush intended (and apologies to TS if it seemed that way) - just trying to provide some assistance and maybe even understand the real requirement.

If this is a test or a training exercise, that's one thing but if mgt makes those kind of directives quite another.

Somewhere between many and most of us who use this forum are "programmers" at some level and if some mgt somewhere provides direction that says code cannot be used by the programmers - it just makes one wonder. . . icon_confused.gif

Sorry to be late to get back to thank you all for u .... uhhhhh .. what i say ... soul crushing advices ....

anyways let me make a point clear... i had a limitation of not using a cobol program coz it was an urgent requirement and movement of the code to production stages would was scheduled to happen after a mont h or so... so for this urgent reuirement all i could use was JCL ....

One advice for u people... if you have a solution to the problem stated on forum only then reply... if u dont have a solution , better shut your mouth and wait for someone to come up with a solution.... i know i must not use the Kind of language i;m using , but it was hilarious to read all the crap you people were putting up ... someone explaining the crap about programs and all.....

i'm a novice in Mainframes to advice you all this ... though i would like to say i'm working for one of the best IT comapany in the WORLD...

anways ... hope you people keep this in mind and the moderators too!!!!

anyways i got the solution for the problem....

no offence intended!!!
cheers!!!

Hey ihatesugar,
maybe you should take some other advice, which would be -
don't upset the contributers to this forum if you want them to assist you in future.

As far as I can tell, the replies to your original query did not supply soulutions as you have demanded because your query was not explicit enough!
As you have conceded belatedly ie
'make a point clear'
'a limitation of not using a COBOL program '
having originally omitted the COBOL bit which makes a big difference!

The rest of the replies were an informal discussion trying to figure out what you were actually asking in the first place.
If we followed your rule, there would be no replies at all because an obvious 'solution' was not possible (based on your scant information.)

Now we all make mistakes and that is understood but until you come back with the correction what are we to do?

Maybe we should fiollow your lead and say .... if you have a query for this forum, make sure you specify it clearly, leave no ambiguity, check that it will be understood.... if you cannot then shut your mouth and don't bother asking for help.

Contributers in the main in this site are trying to be helpful, distribute information and even have a laugh now and again.

This is all done on our own time, we are not forced to do it you know.

Guys like William, Dick, Frank etc spend a lot of time and effort to disseminate their experience thoughout the mainframe community for which they should be thanked and not derided.

Lecture over...

Arrabest!

You are new to mainframe, and someone ( your manager ) or yourself by personal initiative
wants to modify data in production !!! And moreover quickly. Find the error.

New at the point you don't know difference between program and JCL.
I call that "suicide".

One advice for u people
One advice for u guy , I am very proud of my profession, I love it , I am working hard since long time, I am learning every day, I discover always, I also teach some matters and find now very sad that some people just can believe it is "no effort" to work in IT.
No No My work is much much more complex you can just imagine.
It is logic, discipline, stress, huge knowledge, team working, effort, acuteness, obstinacy, and also satisfaction, joy, gratification.

And I am working for one of biggest Bank in the WORLD


So be respectful for people from who you can receive help, and you will receive respect from us too. If ever it is of some interest for you...

That is great, what is it, please post it so that next time somebody has a similar requirement, it can be found by search. Think of it as helping another novice in the future. icon_biggrin.gif

None taken, we all have been there before, frustrated by events and lack of resources.

Please feel free to continue your education, like we all are, by reading these forums and please do not hesitate to ask next time you have a question.

Incidentally, how did you resolve your "Help Required For Use of HEX Values" problem?

Looking forward to your solution,

Bill

Hello IHSugar,

If your IT organization allows/permits you to update production data on the "fly" with no tracking or controls, i can guarantee you it is NOT
Quote:
"one of the best IT company in the WORLD".


As far as your words - it may be that you're just a frustrated rookie. We'll try to overlook that.

Please be assured that really good IT organizations have a formal Emergency Repair Procedure that provides a vehicle to promote code "in the middle of the night". Taking a month to install an emergency fix while allowing someone to toss in some workaround "code" (which is what you did even though you didn't write cobol) is completely nonsense.

Of course you meant offense. Sometimes we talk/type faster than our brain can consider. Most of us won't take offense because we've been really frustrated and know the feeling. We don't always contain ourselves either. . .

Be well and visit again.

Hi ihatesugar,

You didn't tell us what the solution was. I know you don't feel you owe the repliers anything, but the great majority of forum users here may be helped by it just as you hoped to be helped. What say you?

To all,

I hope this thread gets wide readership because it addresses 2 of my 3 pet peeves: 1) the thought that JCL and utils are the same thing, 2) assuming that one sentence will adequately describe a problem (" thanks for your reply but I can't use COBOL in my solution" or I can't do it that way because I'm running it in production) icon_evil.gif

The 3 rd is using "version" when referring to a GDG "generation".

Oops, just thought of a 4th: requestors who disappear w/o a trace after they get their ans. No indication for the other forum members of what worked or how it worked, no thanx, no nothing.
