Answer / vinod
RDW stands for Record Descriptor Word.This is the first 4
bytes in a VSAM - Variable Record Length file that stores
the actual length of the record. This is hidden if you
browse a VSAM file. In a VB file, realistically the record
startsfrom COL 5 and NOT COL 1 as you see when you browse
the file.
