keyboard controls for a gun ship

Personaly I don't use idividual IF statements for all my keys I do this instead...

  If KeyDown(200)=True And y#<9.0
     y#=y#+0.2			
  Else If KeyDown(208)=True And y#>-9.0
     y#=y#-0.2
  End If			
  If KeyDown(203)=True 
     Fire_Jewel_Left()
  Else If KeyDown(205)=True
     Fire_Jewel_Right()
  End IF
