Statement Syntax

Statement Syntax shows the syntax of an assembly language statement. Syntax Elements describes the elements of this syntax.

Listing: Statement Syntax


statement ::= [ 
symbol ] 
operation [ 
operand ] [ ,

operation ::=

operand ::=

Table 1. Syntax Elements
Element	Description
symbol	A combination of characters that represents a value.
machine_instruction	A machine instruction for your target processor.
assembler_directive	A special instruction that tells the assembler how to process other assembly language statements. For example, certain assembler directives specify the beginning and end of a macro.
macro_call	A statement that calls a previously defined macro.
constant	A defined value, such as a string of characters or a numeric value.
expression	A mathematical expression.
register_name	The name of a register; these names are processor-specific.
comment	Text that the assembler ignores, useful for documenting your code.
