Hitachi MK-96RD647-01 manual FXmto with Fixed-Length Record Format

FXmto with Fixed-Length Record Format

Each fixed-length record in a z/OS dataset includes only the fixed-length data entity. The record length defined for a fixed-length dataset equals the actual length of each data entity. The padding option cannot be used for FXmto with fixed-length records.

No padding, no delimiters. Figure 2-9shows an FXmto operation for a fixed-length source dataset. Padding cannot be added to fixed-length records. FCU extracts and transfers the data entities to the open-system target file. The length of each data entity in the target file equals the record length defined for the source dataset.

Source Dataset

Record length
Record 1: Data entity 1
Record 2: Data entity 2	→
Record 3: Data entity 3

Open-System Target File

Figure 2-9 FXmto with Fixed-Length Records: No Padding, No Delimiters

With delimiters. Figure 2-10shows an FXmto operation with delimiters (D) for a fixed-length source dataset. FCU extracts and transfers the data entities to the open-system target file and adds the requested delimiter to the end of each data entity. The resulting length of each data entity in a UNIX target file equals the original record length plus one byte for the delimiter. The resulting length of each data entity in a Windows 2000/2003/Windows NT target file equals the original record length plus two bytes for the delimiter.
