Variable Types
The type of variable is specified by the type declaration character attached at the end of the variable
name.
However, because the names of static variables are determined based on their type, no type
declaration statement is required.
Type Declaration Character Variable Type Specific Examples
$ Character variables STR1$
% Integer variables CONT0%, ACT%(1)
! Real variables CNT1!, CNT1
• If no type declaration character is attached, the variable is viewed as a real type.
• Variables using the same identifier are recognized to be different from each other by the type of
each variable.
• ASP_DEF% ............ Integer variable
)
• ASP_DEF ............... Real variable
→
ASP_DEF% and ASP_DEF are different variables.
• ASP_DEF! .............. Real variable
)
• ASP_DEF ............... Real variable
→
ASP_DEF! and ASP_DEF are the same variables.
4.1 Numeric variables
Integer variables
Integer variables and integer array elements can handle an integer from -2,147,483,648 to
2,147,483,647 (in signed hexadecimal, this range is expressed as &H80000000 to &H7FFFFFFF).
Examples: R1% = 10
R2%(2) = R1% + 10000
Real variables
Real variables and real array elements can handle a real number from –1.0 ×10 38 to 1.0 ×10 38 .
Examples: R1! = 10.31
R2!(2)= R1% + 1.98E3
4.2 Character variables
Character variables and character array elements can handle a character string of up to 255
characters.
Character strings may include alphabetic characters, numbers, symbols and katakana (Japanese
phonetic characters).
Examples: R1$ = "OMRON"
R2$(2) = R1$ + "MOTOR" ··········· "OMRON MOTOR"
MEMO
NOTE
• When a real number is
assigned to an integer
t y p e v a r i a b l e , t h e
decimal value is rounded
off to the nearest whole
number. For details, refer
to Chapter 4 "1.5 Data
format conversion".
NOTE
• The "!" used in real variables
may be omitted .
