7.7 Operators
The following subsections describe the operators used in expressions that are
recognized by the assembler.
recognized by the assembler.
7.7.1 Addition and Subtraction Operators (Binary)
Syntax:
Addition: <operand> + <operand>
Subtraction: <operand> – <operand>
Description:
The + (plus) operator adds two operands, whereas the –
(minus) operator subtracts them. The operands can be any
expression evaluating to an absolute or relocatable expression.
Note that addition between two relocatable operands is not
allowed.
(minus) operator subtracts them. The operands can be any
expression evaluating to an absolute or relocatable expression.
Note that addition between two relocatable operands is not
allowed.
Example:
$A3216 + $42; Addition of 2 absolute operands ( = $A3258)
label – $10 ; Subtraction with value of ‘label’
7.7.2 Multiplication, Division, and Modulo Operators (Binary)
Syntax:
Multiplication: <operand> * <operand>
Division: <operand> / <operand>
Modulo: <operand> % <operand>
Description:
The * (asterisk) operator multiplies two operands, the / (slash)
operator performs an integer division of the two operands and
returns the quotient of the operation. The % (percent) operator
performs an integer division of the two operands and returns
the remainder of the operation.

operation cannot be 0.
expression. The second operand in a division or modulo
operation cannot be 0.
Example:
23 * 4 ; multiplication ( = 92)
23 / 4 ; division ( = 5)
23 % 4 ; remainder( = 3)
