[Coco] Copying over an IO ERROR

[Bill Pierce]

Bill, another thing you can try is file-by-file copying on errored disks. Sometimes in a "BACKUP", the sector errored is not even used in any of the files and using COPY for each file will get all the files without hitting the error.. sometimes...
Just a thought.

By modifying this code a little, can it be made to write directly to a .dsk 
mounted on DriveWire?

Sure would make it easier. I've got a large number of Rainbow on Tape and 
Rainbow on Disk that are damaged, and I'd love just to be able to write them 
directly to a .dsk image.

Thanks

Ah. Two ways:

1. There is a variable that shows the line that had the error, and you could 
"just know" what the line number is.

But better:

2. Expanded to work like this:

XX ON ERR GOTO YYY
XX DSKI$ ....
XX ON ERR GOTO ZZZ
XX DSKO$ ...

END
YYY PRINT "ERROR READING" ...
YYY GOTO ...
ZZZ PRINT "ERROR WRITING" ...
ZZZ GOTO ...
