4.7.
Expressions are a combination of numeric constants, labels/symbols, and
expression operators, which are evaluated by the assembler into a single value.
Expression operators supported are listed below.
All expressions are evaluated using 32-bit calculations.
+
-
*
\
/
^
MOD
AND
OR
XOR
SHR
SHL
Compound operators using the value to the right include:
NOT n
HIGH n
LOW n
OFFSET n Returns the 'lower word (low 16-bit) of n'
UPPER n Returns the 'upper word (high 16-bit) of n'
SWAP n
Comparisons operate on signed values. True returns 0FFFFFFFFH,
False returns 0.
= or EQ
<> or NE
<= or LE
< or LT
>= or GE
< or GT
Expression Syntax

Subtraction
Multiplication.
Division (only Integer part).
Division (rounded integer result)
Potentiation
Remainder of division.
Logical AND operator.
