Specify a record size for a file

RECSIZ:record_size

Arguments

record_size

One of the following values: (n)

n = Set the record size to n for the file being opened.

0 = Ignore the RECSIZ qualifier.

-1 = Set the record size to the length of the first record in the file.

Discussion

The RECSIZ qualifier is only supported for non-ISAM files.

The RECSIZ qualifier sets a record size for the file being opened.

On Windows and UNIX, if you use the RECSIZ qualifier, the records of the file are accessed as fixed-length records of the specified size. By default, the record size of the file being opened is equal to the size of the destination data area on the first I/O operation. Before the first I/O, the record size is undefined.

On OpenVMS, record_size is the record size for the file being opened; the values 0 and -1 are not valid. If you’re creating a relative file on OpenVMS, the RECSIZ qualifier is required. If you’re opening a relative file for input, RECSIZ is not required, but it is checked and an “Invalid record size” error ($ERR_IRCSIZ) occurs if the values do not match. If you are creating a sequential file, this qualifier sets the maximum record size allowed for the file, unless system option #35 is set. If option #35 is set, Synergy DBL accesses the file’s records as fixed-length.

If the file is empty, do not use RECSIZ:-1 to set the record size to the length of the first record in the file.

If the records in the file possibly contain integer data and you want to use RECSIZ:-1, you can put a “dummy” record at the beginning of the file that does not have any integer data. This enables Synergy DBL to determine the correct record size for the file.
