First of all I would like to thank all the people who helped me out last
time on my tile based game question. I got a new hard drive and forgot to
copy all the letters from it, therefore I did not have the return address
and could not thank them. 
I ended up creating a array of values, where each value represented a
terrain. Using this I could redraw only certain squares when the character
moved. (not the whole map)

Second, I've come across another snag. It concerns using the mouse routines
in Allegro. 

  if ((mouse_b & 1) & (mouse_x > fx) & (mouse_x < lx) & (mouse_y > fy) &
(mouse_y < ly))
   CityBackPix();

This is a sample from my code, It basically says that if the mouse pointer
is within a certain range and the mouse button is pressed do the
CityBackPic function. The problem is that it only works if I also press
some button on the keyboard. Because I have other if statements in a
do-while loop I have to press one of them along with the mouse button to
complete the loop and execute the function. When I only want to be able to
press the button and have the function come up.

Again if anyone can help me, please  e-mail me! 

P.S. I'm using the Allegro game libraries, and djgpp as my compiler. 
(Although it probably does not make a difference).
