Creation-Attribute Syntax
AUDITCOMPRESS
compresses the file’s audit trail. For more information, see the TMF Management
Programming Manual.
BLOCK block-length
specifies the block size, in bytes, for both data and index blocks in a structured file.
You can specify block-length either as an integer or as the name of a constant
in the open dictionary. Block-length must be one of the following values:
•
512
•
1024
•
2048
•
4096
Default: 4096 bytes
BUFFERED
writes to your file are buffered in the disk-process cache. BUFFERED is the default
for audited files.
NOBUFFERED
writes to your file written to the disk. NOBUFFERED is the default for nonaudited
files.
BUFFERSIZE buffer-size
specifies the buffer size, in bytes, for an unstructured file. You can specify
buffer-size either as an integer or as the name of a constant in the open
dictionary. The value of buffer-size must be one of:
•
512
•
1,024
•
2,048
•
4,096
Default: 4,096 bytes
CODE file-code
assigns a file code to a file. You can specify file-code either as an integer or as
the name of a constant in the open dictionary. The value of file-code must be
in either of these ranges:
Note: In H06.28/J06.17 RVUs with specific SPRs and later RVUs, a block length of 32768
bytes is also supported. It is only applicable for format 2 key-sequenced files. 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.
