Memory
Address
Address of buffer in memory. On disk read, data is
written starting at this address. On disk write, data
is read starting at this address. On disk format, this
Þeld does not apply.
Block
Number
For disk devices, when doing a format track, the
track that contains this block number is formatted.
This Þeld is ignored for streaming tape devices.
Flag Byte Contains additional information. Bit 0 is
interpreted as follows for disk devices:
If 0, it indicates a Format Track operation.
The track that contains the speciÞed block is
formatted.
If 1, it indicates a Format Disk operation. All
the tracks on the disk are formatted.
For streaming tapes, bit 0 is interpreted as follows:
If 0, it selects a Retension Tape operation.
This rewinds the tape to BOT, advances the
tape without interruptions to EOT, and then
rewinds it back to BOT. Tape retension is
recommended by cartridge tape suppliers
before writing or reading data when a
cartridge has been subjected to a change in
environment or a physical shock, has been
stored for a prolonged period of time or at
extreme temperature, or has been previously
used in a start/stop mode.
If 1, it selects an Erase Tape operation. This
completely clears the tape of previous data
and at the same time retensions the tape.
Address
ModiÞer
VMEbus address modiÞer to use while
transferring data. If zero, a default value is selected
by the debugger. If nonzero, the speciÞed value is
used.
