Record Description Word (RDW) Option
The record description word option can only be used for FXmto operations on
variable-length source datasets. Figure 2-8 shows an FXmto operation with the
RDW option specified. When the RDW option is specified, FCU adds the record
description word in binary code to the head of each record in the source
dataset, and then transfers the data entity with record length bytes to the
open-system target file. The CC, PAD, and DEL parameters must be No; if not,
FCU returns an error. If the RDW option is specified for a fixed-length source
dataset, FCU ignores the RDW option.
Note: If you use FXmto with RDW, the data cannot be transferred back to the
original z/OS dataset (the FXotm target dataset will not be compatible with the
original dataset).
Note: FCU version 01-01-38 or later for UNIX and FCU version 01-01-36 or
later for Windows 2000/2003/Windows NT are required for the RDW option.

VSE Record (VSE) Option
The VSE record option must be used for FXmto and FXotm operations
involving VSE datasets. The VTOC of a VSE dataset does not specify the record
format (RF), record length (RL), or block length (BL) of the dataset. The VSE
record option enables the user to specify these values so that FCU can process
source/target VSE datasets. If you do not specify the VSE record option for a
VSE dataset, FCU will return an error. If you specify the VSE record option and
the RF, RL, and BL are also specified in the VTOC, FCU will process the dataset
if the RF, RL, and BL values are the same, or return an error if the RF, RL, and
BL values are not the same. The VSE record option does not apply to ALC-
generated intermediate datasets.
Note: FCU version 01-01-40 or later is required for the VSE record option.
