MOTOROLA Assembler Syntax 153
7.7.9 Memory PAGE Operator (Unary)
Syntax: Get allocation page: PAGE(<operand>)
Description: The PAGE operator returns the page number where the operand
is allocated. For a valuecoded on four bytes, the PAGE operator
returns the content of bits 23 to 16 of the value.
The operand can be any expressionevaluating to an absolute or
relocatable expression.
When the PAGE operator is used with an absolute expression,
the assembler evaluates the page directly and the value is
written to the output file. In this case, PAGE(<operand>) is
equivalent to <operand> & $FF0000.
Example:
#PAGE($D) ; = 0
#PAGE($15A352) ; = $15
#PAGE(label) ; = Page number where label is
; allocated
7.7.10 Force Operator (Unary)
Syntax: 8-bit address:<<operand>
<operand>.B
16-bit address:><operand>
<operand>.W
Description: The < (less than) or .B operators force the operand to be an
8-bit operand, whereas the > or .Woperators force the operand
to be a 16-bit operand.
The < (less than) operator may be useful to force the 8-bit
immediate, indexed, or direct addressing mode for an
instruction.
