The way buffers are used

Buffers are used when a physical record contains several logical records. Use this parameter to control how M3 SWB handles the buffers. These entries are allowed:

Value	Description
I	The buffer is written immediately to a disk. Each update of a logical record forces the complete buffer (physical record) to be written to a disk.
W	The buffer is only written to a disk when it is full or when M3 SWB needs the buffer for another physical record.
