When run, Display Master will present you with four options: You can load a new Micro-Painter format picture file, or manipulate a previously loaded picture file, or manipulate a built-in moire pattern, or run a demo program. (We'll discuss Micro Illustrator files later.) For now, choose [D] for the demo program.

The solution was to create a lookup table that uses the original byte value as an index into the table, where the corrected pixel mirror image is stored. This also speed reversing the bit order for a given byte. The table is created near the end of the FIND( ) procedure and is declared as byte array REV(256).
