FXmto Operations

An FXmto operation transfers the data from a z/OS dataset on an FX 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 an FX -B or -A volume on the subsystem. 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 version
01-01-40 or later is required for VSE source datasets. FCU supports both

fixed-length and variable-length record formats and provides the following
options for FXmto data transfer (see section entitled “System Requirements”):
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 2-3 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 transferred to

a variable-length or fixed-length target file, depending on the padding option,
and delimiters can also be added if desired.
