NOTE:
Data Exchange supports two kinds of mainframes: MVS and VSE. For Multiple Volume Dataset, Data
Exchange is only supported on MVS.

FXotm Operations
An FXotm operation transfers the data from an open-system file on a Data Exchange volume to a
target dataset on a mainframe volume. The FXotm source file must be located on a Data Exchange
-C or -A volume on the storage system. The FCU does not automatically create the FXotm target dataset.
The target dataset must be created and properly formatted prior to beginning the FXotm operation.
The FCU software performs the FXotm data transfer operations. FCU supports fixed-length and
variable-length record formats for FXotm operations. FCU provides the following options for FXotm
operations (see “
FCU File Transfer Options ” on page 20): code conversion, padding, delimiter, empty
file, and VSE record. The record description word option cannot be used with FXotm. FCU automatically
extracts delimiters from FXotm source files, but cannot add delimiters to FXotm source files. FCU can
add padding only to variable-length FXotm source files. FCU cannot extract padding from FXotm
source files. The types of FXotm operations are:
• FXotm with fixed-length record format
• FXotm with variable-length record format
Table 5 on page 32 specifies the record format requirements for each type of FXotm operation. An
open-system source file with fixed-length data entities can only be transferred to a fixed-length target
dataset. An open-system source file with variable-length data entities must have delimiters and can
be transferred to a variable-length or fixed-length target dataset. If the source file contains padding
from a previous FXmto transfer operation, the padding is transferred to the target dataset along with
the data. If the source file contains delimiters, the delimiters are not transferred to the target dataset.
