The BLOCKSIZE specifier indicates the physical I/O transfer size in bytes for the file. It takes the following form:
BLOCKSIZE = bks
bks |
Is a scalar numeric expression. If necessary, the value is converted to integer data type before use. |
If you specify a nonzero number for bks, it is rounded up to a multiple of 512 byte blocks.
If you do not specify BLOCKSIZE or you specify zero for bks, the default value of 128 KB (131,072 bytes) is assumed.
The default BLOCKSIZE value can be changed by using the FORT_BUFFERSIZE environment variable.
