an excellent idea
For those who would like to know what happens on a 1541-III with a display connected:
nothing happens on the display
, but inside the 1541-III the current file is set to the new open file as refered to as the x in the command stated above.
Then when loading the directory (load"$",8) the display changes to the selected filename of the selected D64 file.
Or when loading a file from the new selected D64 file the display stays unchanged but the file will be loaded. So now the displayed filename of the currently selected file is incorrect (time for a firmware update
This method is excelent in changing the selected .D64 file without loading the directory the conventional way and without pressing the buttons. This is indeed the way to go with special card browsing software.
