at the start of the function i declare bHole as being false. then if
Maze[iX-1][iY].Hole == true i flag bHole as being true. which is used later
in the function to output the relevent txt to the screen.
It is used later in the code so that would mean that the problem is not
because its being optimized right? im using borland builder 6 and that warns
when there are unsued variables but im getting no warnings either
