DEL Option
The DEL 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
DEL 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 DEL 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. “FXmto
Operations” on page 26 and “FXmto with Multiple Volume Datasets” on page 30 describe Data
Exchange 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 1 byte.
• For Windows, you must specify a CR + LF. The length of this delimiter is 2 bytes.
NOTE:
Do not use the DEL option for FXotm if the source file contains the same characters as the delimiter
but are being used for a purpose other than delimiting data entities. If you do, FCU will interpret
the specified delimiter characters as delimiters, which can create a target dataset with corrupt
records or generate an error condition.
NOTE:
When you use FXmto with DEL (no padding) for variable-length records, the data can be transferred
back to the original mainframe dataset later using FXotm.
Emp) Option
The Emp) option can be used for both FXmto and FXotm operations. When the Emp option is specified,
FCU processes an empty source file instead of returning an error. An empty mainframe dataset is a
dataset that has no records or only EOF records. An empty open-system file is a file that has a file
size of 0 bytes. When an empty mainframe 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.
RDW Option
The RDW option can only be used for FXmto operations on variable-length source datasets. Figure
8 on page 26 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.
