The interesting thing about the BBC is that its BASIC interpreter allows
in-line assembler code.
60 .START LDA #&FF
70 STA H%
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
