SETMODE Procedure
99 TAPEPROCESS error recovery method
param1
= 0 record level recovery (default)
The record is written to tape as soon as it is received.
= 1 file level recovery
Data is buffered at the drive until an end-of-file mark is
received. The data is then flushed from the drive buffer
to the tape media.
= 2 volume level recovery
Data and end-of-file marks are buffered until the device
sees two consecutive end-of-file marks or a
tape_synch. The device buffer is then flushed from the
drive buffer to the tape media.
Once set, the buffering method remains set until changed or until the
application issues a FILE_CLOSE_ on the device corresponding to a
previous FILE_OPEN_. At that time the buffering is reset to record-level at
the device.
param2 is not used with function 99.
