By inserting 200 bytes of low values, do you want to increase the length of file by 200 bytes or you want to replace the 200 bytes starting from position 100 ?

You may try the below code:

Or use OVERLAY: Reformat each record by specifying just the items that overlay specific columns. Overlay lets you change specific existing columns without affecting the entire record.

hikaps14,

Your control statements would NOT work. Please don't post untested code.

Trumpcards,

You could use these DFSORT control statements if you want to insert 200 binary zeros:

Apologies for posting an untested job.

Since it's a variable length file (VB), the records can vary in length. They will not necessarily all be 500 bytes - that's the maximum length. Specifying the position (p) without the length (m) at the end of the BUILD operand ensures that records are copied from that position to the end of the record, whatever the size of the record is.
