Marko, this is all great stuff you're giving me, thanks for the info!

I see the idea here.  I'm a little confused as to how the file would
look though.  How do I mix in the ASM and BASIC together in a single
file?  Am I relying on the default load address for a BASIC program
and counting the bytes for the BASIC tokens as the "header" of my
assembly code?  Is that why the "NEW" version has a start address of
$040F and the other has a start address of $040D?
