Morning all

I've slowly been working my way through learning C and DJGPP, and I was 
wondering if it's possible to use a Case statement to check for a range of 
numbers - not just one....

eg..

Switch (bullet_x)

  Case (alien1_x to alien1_x + 16)
	then alien_hit = 1
  Case (alien2_x to alien2_x + 16)
	then alien_hit = 2
  Default
	alien_hit = 0

I guess I'm trying to do a 'bounding box' (?) check to see if a player 
bullet has hit an alien sprite anywhere along it's width.  I'm doing a 
space invaders game where the players bullet just goes straight up the 
screen.

Thanks
