8.7Expressions

Expressions are symbols, self-reference address symbols, and constants linked by operators, with the result representing a single value. When an expression is coded as an operand, its result will be a number or an address depending on the type of instruction.

When a symbol or self-reference address included in an expression is a forward referenced symbol, a relocatable symbol, or an undefined symbol, the result of the expression cannot be resolved by the assembler. It will then be resolved by the linker.

NOTE:	If a section name in the expression was used as a symbol, declaration with the
	section directive must be done in the file. Without doing this would lead an error
	in the assembler or linker.
	Example:	section CODE,PUBLIC,1
	sec
	_TEXT	section CODE,PUBLIC,1
		mov	sec, A0
