[Coco] Not quite a CoCo, but interesting!

[Bob Devries]

The interesting thing about the BBC is that its BASIC interpreter allows 
in-line assembler code.

For example:
50 [OPTZ%
60 .START LDA #&FF
70 STA H%
...
260 RTS
270 ] : NEXT

The assembler code is able to directly reference BASIC's variables. The 
assembler does two passes, and can if desired print a listing. I don't 
remember other options (see line 50 above). This would have been great for 
the coco. SIGH.

Oh, BTW, did I tell you I own one? :P
