Addressing Rules and Examples
Chapter 4
4Ć13
1. A remote address can be used only with the single equals sign (=)
type of assignment command.
2. In the assignment command, either the source or the destination, but
not both, may be a remote address.
3. A remote address may contain an embedded expression, but a remote
address may not be embedded in an expression.
Expressions use operators to combine two or more numeric values into a
single value. Table 4.B lists the operators that can be used in an
expression. These operators are listed from highest priority (1) to lowest
priority (10). Expressions may be nested within other expressions by
enclosing the inner expression within parentheses.
