5.3.2 Data Types and Register Specifications
There are five kinds of data: Bit, integer, double-length integer, real number, and address data. Each
is used differently depending on the application. Address data, however, is used only inside functions
when specifying pointers. The following table shows the types of data.

ta Types and Register
ecifications
A digit to indicate the bit (A) is added to
the register number (00103).
The words for the given register nu
(00102) and the next number (001
included. Therefore, every second
is used.
