[Coco] Cross Post from FB Page..Disk Basic Programming Question...

[Arthur Flexser]

You could try opening the disk file with a certain device number assigned
to it and then poke that device number into location $6F immediately before
doing the LLIST or DIR (restoring the device number to zero afterwards) and
see if that works for getting the output into the disk file.
