[Coco] 4K CoCo 1 & EDTASM+

[William Astle]

You have to use the "/SR" assembly option I believe. The EDTASM manual 
should talk about that somewhere.

Color Basic doesn't support multi-origin binaries. That support came 
with Extended Basic which supports a format for CLOADM that is basically 
the same as Disk Basic uses. That format supports multi-origin.

Basically, the /SR assembly option creates a binary that Color Basic can 
load. Otherwise, the default format is the one supported by Extended 
Basic I believe.

The major caveat is that your program must be in a single chunk that 
loads at a single address.
