lwasm defaults to "org 0" so if it is working without an ORG statement, 
it's only working by accident.

With a default configuration of disk basic, putting the code anywhere 
between $e00 and $2600 should work fine because that is within the 
default 4 pmode graphics pages. If you don't need to preserve a basic 
program, you can clobber anywhere from $e00 up to about $3c00 fairly 
safely (asuming 16K) or $7c00 (assuming 32K).

If you put the binary created by lwasm on a disk image and use LOADM and 
EXEC to start it, it should work just fine. If you're using some other 
method, it may be that method is not doing the expected thing.
