NOTE:
If you use FXmto with RDW, the data cannot be transferred back to the original mainframe dataset
(the FXotm target dataset will not be compatible with the original dataset).

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 RF), RL, or 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.
FXmto Operations
An FXmto operation transfers the data from a mainframe dataset on a Data Exchange volume to an
open-system file on an open-system LU. The object data entities are those contained in all records
between the beginning of the file and the end of the file. The end of a dataset is the EOF record or
the end of the final extent. The end of an open-system file is the EOF. The FXmto source file must be
located on a Data Exchange -B or -A volume on the storage system. If the specified FXmto target file
does not exist, FCU automatically creates the target file during the FXmto operation. If the specified
FXmto target file already exists, FCU requests confirmation to overwrite the target file (unless the -nc
option is specified).
The FCU software performs the FXmto data transfer operations. FCU supports both fixed-length and
variable-length record formats and provides the following options for FXmto data transfer (see “
System
Requirements ” on page 49): code conversion, padding, delimiter, empty file, record description word,
and VSE record. The types of FXmto operations are:
• FXmto with fixed-length record format
• FXmto with variable-length record format
Table 3 on page 27 specifies the record format requirements for each type of FXmto operation. A
fixed-length source dataset can only be transferred to a fixed-length target file, with or without delimiters.
Padding cannot be added to a fixed-length source file. A variable-length source dataset can be
