More Open Commodore Files

The "64 Explorer" by Larry Isaacs in the March 1984 issue concerning the maximum number of files which can be open at one time on the 1541 disk drive caught my interest. I have discovered some further information.

The number of sequential files opened for writing can be increased to three if the filename is prefixed with a 0:. When this is not the case, the drive acts as Isaacs described.

Since the Disk Operating System was originally used on a dual disk drive, I always add the prefix 0: to any disk operation to insure that it will work properly.
