Improved Directory Printouts

When you list your directory to the printer, the disk name prints in reverse field (white letters on a black background), which is not too legible on Commodore printers, and which totally confuses some others.

The reverse field effect can be eliminated by a simple direct mode command executed after the directory has been loaded.

The POKE is to an address five bytes above the start of the BASIC program area, and replaces the reverse field character with a space. On some machines, the previous execution of certain graphics statements causes the start of BASIC to move, so we have included a GRAPHIC CLR to undo the move. In most cases it can be omitted without any adverse effect.
