76 >The LW tool chain provides utilities for building binaries for MC6809 and | |
77 HD6309 CPUs. The tool chain includes a cross-assembler and a cross-linker | |
78 which support several styles of output.</P | |

88 >For a long time, I have had an interest in creating an operating system for | |
89 the Coco3. I finally started working on that project around the beginning of | |
90 2006. I had a number of assemblers I could choose from. Eventually, I settled | |
91 on one and started tinkering. After a while, I realized that assembler was not | |
92 going to be sufficient due to lack of macros and issues with forward references. | |
93 Then I tried another which handled forward references correctly but still did | |
94 not support macros. I looked around at other assemblers and they all lacked | |
95 one feature or another that I really wanted for creating my operating system.</P | |
96 ><P | |
97 >The solution seemed clear at that point. I am a fair programmer so I figured | |
98 I could write an assembler that would do everything I wanted an assembler to | |
99 do. Thus the LWASM probject was born. After more than two years of on and off | |
100 work, version 1.0 of LWASM was released in October of 2008.</P | |
101 ><P | |
102 >As the aforementioned operating system project progressed further, it became | |
103 clear that while assembling the whole project through a single file was doable, | |
104 it was not practical. When I found myself playing some fancy games with macros | |
105 in a bid to simulate sections, I realized I needed a means of assembling | |
106 source files separately and linking them later. This spawned a major development | |
107 effort to add an object file support to LWASM. It also spawned the LWLINK | |
108 project to provide a means to actually link the files.</P | |
