Hi

For one of the requirment, I wanted to copy a FB dataset to new file of RECFM VB. But while copying I need to split the any existing record, to a create a new record, on every occurance of x'10'. Can someome please guide me on this. Thanks

How many records may there be? Record-length? Can logical records split across physical records? Where do the X'10' come from? Why can't the split be done there?

Can you please explin it again?

103 records for test data and that much we anticipate. Record-length is 100 for both input and output.

You want to split records based on X'10'. For the final X'10' on a record, does all the data follow on that same record, or is there some data on the next record.

How many X'10's can you have? 49? Some lower number?

We can have around 21 X'10' not more than that. But why do you mention 49? Is there some constraint on that number?

For final record there can be some dara on next record.

just a generic placeholder for the number of X'10' to process

You said you have 100-byte records. 100/2 = 49 (since you didn't say if that was F or V records).

The "limit" is the number of "records" which can logically exist. If the smallest record, including the X'10', is 10 bytes, you could have a maximum of 10 per records (assuming F, else nine per record if V).

100/2=50, is not it?

I think I got you wrong last time and if I'm getting you correctly now, in a record, only one occurence of X'10' is possible.
