T: Data access type
hhhh: Addresses of Data (in hexadecimal)
b: Bit number for bit-type data access (in hexadecimal)
Example)
#PL0000 = 10000;
MOVE_[J01]#PL0000;
Use 4-digit hexadecimal notation for data addresses.
Data addresses indicate the first address of integer data regardless of the
access type.

Odd-number addresses cannot be specified with Double-length integer type
or Real number type. Make sure to specify even-number addresses.
Followings are the examples:
• (1) ML0000 = 1234 --- Write 1234 in the Double-length integer type.
• (2) MF0000 = 1234 --- Write 1234 in the real number type.
