Hi,

I have to copy a VB to a new VB file. In this, I need to see if there is a records of length of 500 then I need to make it 480. Is that possible using SORT. Please help me.

How do you identify which record of 500 bytes is to be reduced in length - if there are more than two types. Which 20 bytes are not to be copied? Does the 500 bytes include the RDW?

I don't know whoe to check on the lenght. But every record will have RDW.

if there are more than two types

I did not get you. Can you please explian it again.

You will have some records of 500 (or 496 or 504) bytes. You intend to lose 20 bytes. Which ones? Are they all the for same type of record (nicc's point)? If not, how are the records you want to lose data for identified?

I forgot to tell the main information, the LRECL is 1000 and it should remain same after copy too. I need to find all the records which are of length 500 in the current file and last 20 butes should be removed while we copy it to output.

You need, on INREC, to have IFTHEN=(WHEN=(logicalexpression to test the record-length part of the RDW on each variable-length record for being 500, in binary (you define the field as binary). Then you BUILD=(1,4,5,476) and that is it.

Thanks William.
