 == Introduction
-At the end of [[SD-8516 Stellar BASIC]] we wrote a game called [[sdb:robots|ROBOTS.BAS]]. This was a fun little take on the classic CHASE or 'robots' game from the bsd games collection. Now, for our study of Assembly Language, let's write a similar game: 'robots.asm'.

Now, for our study of Assembly Language, let's write a similar game: 'robots.asm'. Don't worry if you're not familiar with the BASIC version of this program; everything will be explained here.
 == Part 1: Assembling and Running a Program
-An assembly language program should start with an .address the bytes will be compiled from. Our program therefore begins:
+Just like BASIC programs have line numbers, or C programs have #include statements, an assembly language program should start with an ''.address'' statement. This will tell the assembler where to start assembling the program. This enables us to use labels like ''start:'' and ''message:''. The assembler can calculate the exact address of the label in relative to the ''.address'' when assembling the program.
