Relational Operators
For use only in conditional assembly expressions.
Boolean Operators
HIGH and LOW Operators
The HIGH and LOW operators can be used to extract specific bytes from an integer
expression. The LOW operator extracts the byte starting at bit 0 of the expression, while
the HIGH operator extracts the byte starting at bit 8 of the expression.
HIGH and LOW can also be used to extract portions of a floating-point value.
For example:
# LOW (X) ; 8 least significant bits of X

# HIGH (X) ; 8 most significant bits of X
The syntax of these operators is:
<operator> <expression>
For example:
== Equal Synonyms: .eq., .EQ.
!= Not Equal Synonyms: .ne., .NE.
> Greater Than Synonyms: .gt., .GT.
< Less Than Synonyms: .lt., .LT.
>= Greater Than or Equal Synonyms: .ge., .GE.
<= Less Than or Equal Synonyms: .le., .LE.
& Bitwise AND Synonyms: .and., .AND.
| Bitwise inclusive OR Synonyms: .or., .OR.
