79 ><P
80 >&#13;Since version 2.5, LWASM is able to generate OS9 modules. The syntax is
81 basically the same as for other assemblers. A module starts with the MOD
82 directive and ends with the EMOD directive. The OS9 directive is provided
83 as a shortcut for writing system calls.&#13;</P
84 ><P
85 >&#13;LWASM does NOT provide an OS9Defs file. You must provide your own. Also note
86 that the common practice of using "ifp1" around the inclusion of the OS9Defs
87 file is discouraged as it is pointless and can lead to unintentional
88 problems and phasing errors. Because LWASM reads each file exactly once,
89 there is no benefit to restricting the inclusion to the first assembly pass.&#13;</P
90 ><P
91 >&#13;It is also critical to understand that unlike many OS9 assemblers, LWASM
92 does NOT maintain a separate data address counter. Thus, you must define
93 all your data offsets and so on outside of the mod/emod segment. It is,
94 therefore, likely that source code targeted at other assemblers will require
95 edits to build correctly.&#13;</P
96 ><P
97 >&#13;LWLINK does not, yet, have the ability to create OS9 modules from object
98 files.&#13;</P
