Specifications for DisplayBoard

Function DisplayBoard$(Mode$)

if Mode$="BW" then display for Both players and return immediately with DisplayBoard$="".

Otherwise,
if Mode$="W" then display for white
if Mode$="B" then display for black
After display, get a move attempt from the player.
Legal values for DisplayBoard$ are "resign" and
"a1-b3" <---etc. a-h, 1-9

There is no need for DisplayBoard to evaluate the move, so I removed the LegalMove simulation from this thread as useless clutter. :-)

The driver is posted in reply to this. Simply remove the DisplayBoard$ function and insert your own. Keep all the rest of the driver as-is to avoid integration problems.
