Explanation

For Variable Blocked (VB) files in mainframe JCL, you need to add 4 bytes to the maximum record length for the RDW (Record Descriptor Word). If your actual data record is 25 bytes, LRECL must be 25 + 4 = 29. The 4-byte RDW precedes each record and contains the record length information. This is a standard requirement for variable-length datasets.
