Note: If you use FXmto with padding, the data cannot be transferred back to
the original z/OS dataset (the FXotm target dataset will not be compatible with
the original dataset). If you use FXotm with padding, the delimiter option is
required.
Delimiter (DEL) Option
The delimiter option can be used for both FXmto and FXotm operations and
enables variable-length records to be transferred between platforms without
losing compatibility with the original dataset. When the delimiter option is
specified for FXmto, FCU adds the specified delimiter to the end of each data
entity in the source file, and then extracts and transfers the data entity with
delimiter to the open-system target file. When the delimiter option is specified
for FXotm, FCU extracts each data entity preceding the specified delimiter and
transfers the data entities without delimiters to the target dataset. Sections
FXmto Operations and FXmto with Multiple Volume Datasets describe FX
operations with delimiters.
The type and length of the delimiter added (or recognized and extracted) by
FCU depends on the open-system platform:
• For UNIX-based platforms, you must specify either a carriage return (CR) or
a line feed (LF). The length of this delimiter is one byte.
• For Windows 2000/2003/Windows NT, you must specify a CR + LF. The
length of this delimiter is two bytes.
Note: Do not use the delimiter option for FXotm if the source file contains
the same character(s) as the delimiter but used for a purpose other than
delimiting data entities. If you do, FCU will interpret the specified delimiter
character(s) as delimiters, which can create a target dataset with corrupt
records or generate an error condition.
Note: If you use FXmto with delimiter (no padding) for variable-length
records, you will be able to transfer the data back to the original z/OS dataset
later using FXotm.
Empty File (Emp) Option
The empty file (Emp) option can be used for both FXmto and FXotm
operations. When the empty file option is specified, FCU processes an empty
source file instead of returning an error. An empty z/OS dataset is a dataset
which has no records or only EOF records. An empty open-system file is a file
which has a file size of 0 bytes. When an empty z/OS dataset is processed, the
open-system target file size = 0. When an empty open-system file is
processed, the target dataset will contain only EOF records.
