The only way to make multiple cameras in DarkBasic Classic Is to alternate the camera position between two locations and set the visible area of the screen for each position and angle.
Cam#=Cam#+1
If Cam#=3 then Cam#=1
If Cam#=1
Position Camera 1st location
Rotate Camera 1st Angle
Set View 1st half of screen
Endif
If Cam#=2
Position Camera 2nd location
Rotate Camera 2nd Angle
Set View 2nd half of screen
Endif
Note that this meathod will cut your FPS(Frames per second) in half...Well...I hope that answers your question.
