There are a couple of ways to conditionalize code based on the runtime
1) In script, you can look at these constants that the compiler sets
$runtime := swf7,swf8,swf9,dhtml,svg
And these are booleans that will be set depending on runtime
$swf7
$swf8
$as2
$swf9
$as3
$dhtml
$j2me
$svg
$js1
example:
// this is used for compatibility between swf and dhtml runtimes
if ($as2) {
var encodeURIComponent = escape;
}
example using #include
if ($dhtml) {
#include "kernel/dhtml/Library.lzs"
} else if ($svg) {
#include "kernel/svg/Library.lzs"
} else if ($as2) {
#include "kernel/swf/Library.lzs"
} else if ($debug) {
Debug.error('kernel/Library.lzs unsupported runtime %s', $runtime);
}
2) In LZX code, there is a special <switch> tag, which can be used to
conditionally
compile code based on the runtime
Example
<switch>
<when runtime="dhtml">
<!-- no debug window in DHTML, it is in its own iframe -->
</when>
<otherwise>
<include href="debugger.lzx"/>
</otherwise>
</switch>
