CROSS ASSEMBLER->Assembler Expressions->Assembler Expressions
Expressions are placed in the operand field and are evaluated by the cross-assembler to give a numerical integer value. An expression may be used anywhere within the operand field where a numerical value is expected. The expression evaluator within the cross-assembler will use 32 bit integer arithmetic to calculate the value of the expression.
The expression may consist of symbols, numbers, literals and operators. Parentheses may be used to define a particular order of precedence. Parentheses can be nested.
The following operators are allowed:
Addition | + | |
Subtraction | - | |
Multiplication | * | |
Integer division | / | |
Modular division | MOD | |
Logical OR | OR | |
Logical AND | AND | |
Logical exclusive OR | XOR | |
Complement | NOT | |
Shift right | SHR | |
Shift left | SHL | |
Select high order byte | HIGH | |
Select low order byte | LOW | |
Equal | EQ or = | |
Not equal | NE or <> | |
Less than | LT or < | |
Less than or equal to | LE or <= | |
Greater than | GT or > | |
Greater than or equal to | GE or >= |
