Package mars.assembler.token

Class SourceLine

java.lang.Object

mars.assembler.token.SourceLine

public class SourceLine
extends Object

Handy class to represent, for a given line of source code, the code itself, the program containing it, and its line number within that program. This is used to separately keep track of the original file/position of a given line of code. When .include is used, it will migrate to a different line and possibly different program but the migration should not be visible to the user.
