[Coco] HDB-DOS-Drivewire 3

[Boisy Pitre]

Bob,

That sounds like the functionality we need.

You took a stab at adding some functionality to some utilities in the  
NitrOS-9 project some time back. Do you think you could add this to  
our current megaread?  I would envision a syntax like this:

megaread ###  (where ### is a decimal number of 1K blocks to read)  If  
no option is given, then the default would be 1024 blocks.

Regards,
Boisy G. Pitre
