screenZ()
Sets the screen order in which screens are refreshed on display by
sdlBasic. If z parameter is omitted, it returns the current screen z
position. Think about z position as the screen deep on display. Screens
having greater z position will be displayed behind those screens having
smaller values.
Syntax:
variable
= screenZ(
bob
)
screenZ(
bob
,
z
)
z may range from 0 to the maximum screen number (7)
