i have some doubts in jcl. can anyone solve it?

1.What is the advatage of coding RECFM=F over RECFM=FB.

2.How to by pass the step without cond parameter?

3.How can be determined if date contained in the header of a file is date current date?

4.There are a set of 10 files and a customer will be selecting random no of files(i.e they may be more than 2, may not be in the order).Sometimes he might just select one file or sometimes no files at all.How do you code a JCL for this? Is it possible to code just JCL alone for this problem?

The only "advantage" I can think of is that the buffers will be smaller. I guess if I used my imagination I could come up with an app where it would come in handy.

"I have an app that requires 30,000 1 rec inputs to be open concurrently ...."

Hi Jack,

Sure hope i don't slip up and say that at the airport. . .

Is that app proprietary? I've gotta get me one of those. . . .

Hi Friend

1.There are a set of 10 files and a customer will be selecting random no of files(i.e they may be more than 2, may not be in the order).Sometimes he might just select one file or sometimes no files at all.How do you code a JCL for this? Is it possible to code just JCL alone for this problem?

If we know the files names and the number of files are fixed then we can concatenate the files ,need to concatenate with a Dummy file to handle the sutuation in case of 0 files

In general Assembler routines are used to open the files dynamically & write into the files by creating them dynamically in the program.

The same can be done through REXX .

Hi Jack,

Good humor seem to fade away fairly quickly - bad jokes (especially those that fit us) follow us a long, long time. . . .

'Preciate the offer to provide the app, but if the price is only $1.00 per input, i'll look around until i find one that will hurt more to purchase as well as eat the machines. It's a shame that Windows apps don't run on the mainframe - quite a few of them appear to have used that design criteria

Hi Dick,

Dont get me wrong, it was a good joke. But it seems that jokes seem to fade with age and use.

I'll bet "Take my wife.... Please" was a good joke once.
