[Coco] batch file processing

[Bob Devries]

Hi Wayne,

Given you can produce two text files, one for each disk, it seems to me that 
you could use DIFF to show you the differences. Diff is not a usual OS-9 
utility, but should be available one one of our FTP sites.

I did a quick search of RTSI, but didn't spot it. If someone knows where it 
is residing, please speak up.

Regards, Bob Devries
