SET

Description

The SET directive assigns a numeric value or register symbol to a specified symbol name. Statements involving the SET directive are formatted as follows:

symbol  SET  expression

symbol  SET  register

where:

symbol    is the name of the symbol to define. The expression  or register  specified in the SET statement replaces each occurrence of the symbol  that is used in your assembly program.

expression    is a numeric expression which contains no forward references.

register    is one of the following register names: A, R0, R1, R2, R3, R4, R5, R6, or R7.

Symbols defined with the SET directive may be used anywhere in operands, expressions, or addresses. Symbols that are defined as a register name can be used anywhere a register is allowed. The A51 assembler replaces each occurrence of the defined symbol in your assembly program with the specified numeric value or register symbol.

Symbols defined with the SET directive may be changed by subsequent SET statements.
