NOFILEFORMAT
For files with no format specification, the maximum allowed record length (assuming
the block size as 4096 bytes) is:
If you attempt to define a record size that is greater than the above specified record
sizes, the DDL compiler issues an error message.
File type Record size (<2GB file)
Unstructured 4096 bytes
Key-sequenced 4062 bytes*
Entry-sequenced 4072 bytes
Relative 4072 bytes
*
In H06.28/J06.17 RVUs with specific SPRs and later
RVUs, the supported maximum record length (assuming
the block size as 32768 bytes) for a key-sequenced file is
27648 bytes.
For a list of the required H06.28/J06.17 SPRs, see SPR
Requirements for Increased Enscribe Limits for the
H06.28/J06.17 Release.
Note: In H06.28/J06.17 RVUs with specific SPRs and later RVUs, you must explicitly specify
the block size as 32768 bytes for a record length exceeding 4062 bytes.
