Relationships between devices and addresses
2. 32-bit operation (DBINDA/DBINDAP)
1) Each digit of 32-bit binary data stored in the device specified by is converted into an ASCII code
(30H to 39H), and stored in the device specified by and later.
For example, when the device specified by stores "-12,345,678", the conversion result is stored in
the device specified by and later as follows:
2) The numeric range of 32-bit binary data stored in the device specified bay is from "-2,147,483,648"
to "2,147,483,647".
3) The conversion result stored in the device specified by is as follows:
a) As "sign data", "20H (space)" is set when the 32-bit binary data stored in the device specified by
is positive, and "2DH (-)" is set when 32-bit binary data stored in the device specified by is
negative.
b) "20H (space)" is stored for "0" on the left side of the effective digits (zero suppression).
c) The high-order byte of + 5 is set as follows depending on the ON/OFF status of M8091.
ON/OFF status Contents of processing
M8091=OFF
The high-order byte of + 5 is set to "00H (NULL)".
M8091=ON
The high-order byte of + 5 is set to "20H (space)".
*1. This defines the device that stores binary data to be converted into ASCII codes.
*2. This defines the head device that stores the conversion result.
