Record Descriptor
Words (RDWs) are the first 4 bytes at the start of a variable record
length file that tell the reading program the actual length of the
current record being read. Use the RDW statement to specify whether
the RDW from variable format data sets should be retained as data
and transmitted or not transmitted.
- Server
- This setting applies when transferring data sets from the server's
system.
- Client
- This setting applies when transferring data sets from the client's
system.
Syntax
.-RDW FALSE------.
>>-+----------------+------------------------------------------><
'-RDW--+-TRUE--+-'
'-FALSE-'
Parameters
- TRUE
- Record descriptor words are transferred as data. FTP returns the
RDWs as part of the data for variable record format data sets. Depending
upon the FTP implementation, RDWs might not be handled as the user
expects. For example, the z/OS® Communications
Server
FTP client might treat received RDWs as as carriage control/line feeds.
- FALSE
- Record descriptor words are not transferred with the data.
Examples
To specify that a variable record
format file's data is transmitted without the descriptors showing
the way it was stored on
z/OS, use
the following code:
RDW FALSE
