5.14 Alpha SDA Commands, Parameters, and Qualifiers
Qualifier Meaning
/COUNT=[{ALL|records}] Gives the number of records to be
displayed. The default is to display
all records.
/DECIMAL Outputs data as decimal values.
/FORWARD Causes SDA to display the records
in the history buffer in ascending
address order. This is the default.
/HEXADECIMAL Outputs data as hexadecimal values.
This is the default.
/INDEX_ARRAY [={LONGWORD
(default)|QUADWORD}]
Indicates to SDA that the range of
addresses given is a vector of pointers
to the records to be displayed. The
vector can be a list of longwords
(default) or quadwords. The size
of the range must be an exact
number of longwords or quadwords as
appropriate.
/INITIAL_POSITION
={ADDRESS=address|RECORD=number}
Indicates to SDA which record is to
be displayed first. The default is the
lowest addressed record if /FORWARD
is used, and the highest addressed
record if /REVERSE is used. The
initial position may be given as a
record number within the range, or
the address at which the record is
located.
/LONGWORD Outputs each data item as a
longword. This is the default.
/PHYSICAL Indicates to SDA that all addresses
(range and/or start position) are
physical addresses. By default,
virtual addresses are assumed.
/QUADWORD Outputs each data item as a
quadword.
/RECORD_SIZE=size Indicates the size of each record
within the history buffer, the default
being 512 bytes. Note that this size
must exactly divide into the total size
of the address range to be displayed,
unless /INDEX_ARRAY is specified.
/REVERSE Causes SDA to display the records
in the history buffer in descending
address order.
