2. Arithmetic Operator
An arithmetic operator performs an arithmetic operation, exponent operation, or remainder operation on
numerical value data, Division by 0 results in an error. If the interim result of an arithmetic operation such as
addition, subtraction, or multiplication is outside the range -1.0e30 to 1.0e30, an error will result.
Arithmetic operators that can be used in macro customize functions are shown below.
Operator

-
*
/
^
mod
3. Relational Operator
A relational operator compares two numerical data items or two character data items. If the result of the
comparison is true, (-1) is returned. If false, (0) is returned. Normally this is used in an "If - Then" statement
for such purposes as controlling the flow of the program.
Relational operators that can be used in macro customize functions are shown below.
Operator
=
<>, ><
<
>
<=, =<
>=, =>
Note
When "=" is used in other than a conditional comparison such as an "If - Then" or "Select" statement, "=" is treated as a
assignment operator that assigns the value on the right side to the left side.
4. Logic Operator
A logic operator is used to investigate multiple conditions, and perform bit operations and binary operations
on exponential values. Logic operators that can be used in macro customize functions are shown below.
Operator
NOT
AND
OR
XOR
