[Coco] Ghana Bwana on my Coco3 not working but ok on Coco2

[John Donaldson]

DSKI$, DSKO$, and MID$ are Disk Basic commands. Thus you have to take 
the statements and make a Basic program out of them. Then run the Basic 
program.

10 DSKI$ 0,34,A$,B$
20 MID$(A$,106,1)=CHR$(254)
30 MID$(A$,122,1)=CHR$(254)
40 DSKO$ 0,34,A$,B$
