(c) Data table head address
Sets head address in the data table.
The memory of (byte length) × (number of data table elements)
which was set in "(a) Format specification" and "(b) Storage
address of number of data table elements" is necessary.
(d) Input/Output data storage address
In case of the reading, set the address of the memory which
stores a reading result. In case of the writing, set the address of
the memory which stores a writing result. The memory with the
byte length which set in "(a) Format specification" is necessary.
When setting format specification in the extended format, set the
head address of the array. (In case of the reading, set the head
address of the array in which a reading result is stored. In case of
the writing, set the head address of the array in which a writing
result is stored.) The memory of (byte length) × (number of
index array elements) which was set in "(a) Format specification"
is necessary.
(e) Index storage address
Set the address of the memory in which an index value is stored.
The memory with the byte length set in "(a) Format
specification" is necessary. The effective range of number of
data in index is as follows according to the byte length set in "(a)
Format specification".
Actually, set the value which is smaller than the value to set in
"(b) Storage address of number of data table elements" to the
index.
When setting an index value above the value to set in "(b)
Storage address of number of data table elements", it causes an
error output W1 = 1 in instruction execution.
1 byte length: 0 to 254
2 byte length: 0 to 32,766
4 byte length: 0 to 2,147,483,646
When setting format specification in the extended format, set an
address at the head of the array in which an index value is stored.
The memory of (byte length) × (number of data in index array)
which was set in "(a) Format specification" is necessary.
