(2) Structural description of programs
Use of the index register and edge relay enables easy structured programming including the pulse conversion
processing. ( Section 9.2.6)
(3) Easy data processing
(a) Using real numbers and character string constants without conversion
Real numbers (floating-point data) and character string constants can be used without conversion for
programming.
*1: The NULL character represents "00H" (end of character strings).
(b) High-speed processing of bulk data
Extension of the data table operation instructions, such as the data table processing instruction, allows high-
speed processing of bulk data.
