Arithmetic Operation Function 1
This function allows arithmetic operation using variables. The programming can be done in the
same way as for general arithmetic expressions.
[Program format]
Address character, Extended address character, Variable = Expression
The expression on the right-hand side, requesting an arithmetic operation, is made up of constants,
variables, comparison expressions, and operators.
The arithmetic and comparison expressions are described below.

(Less than or Equal to,
≤
)
IF [V1 LE 5] N100
Jump to N100 when V1
is less than or equal to 5.
EQ
(EQual to, =)
IF [V1 EQ 5] N100
Jump to N100 when V1
is equal to 5.
NE
(Not Equal to,
≠
)
IF [V1 NE 5] N100
Jump to N100 when V1
is not equal to 5.
GT
(Greater Than, >)
IF [V1 GT 5] N100
Jump to N100 when V1
is greater than 5.
GE
(Greater than or Equal,
≥
)
IF [V1 GE 5] N100
Jump to N100 when V1
is greater than or equal
to 5.
