This instruction defines the surface properties of a given rectangular area. Note, you cannot 'harden' an elevated surface with this command! Use aditional section 16 commands for this.

Defines a new starting point for roads and rivers. Road and rivers are normally covered with textures.
This command should always be followed by an: RoadCont() or RiverCont() command which are equal to the old RoadLineTo() command.

Every ..Move../..Start instruction sets the starting point of a road or taxiway relative to the active reference point. The ..Line../..Cont instruction draws a road or taxiway from the previous point to the point defined in this instruction and stores his position as a starting point for an following ..Line../..Cont instruction.
During dusk and nights roads have orange lights and taxiways have blue lights. The color can be chosen by SurfaceColor().
If a texture is loaded just before these drawing commands the river or taxiway is drawn with this texture. You can use TextureEnable( 0 ) to disable this texture.

For FS2000 use RRStart() for roads and rivers.

Sets a local variable

This command sets a global variable.

Defines an elevated hard surface i.e. for a runway on a mountain. Elevated surfaces produced by this command are always smooth (good for runways). This instruction was only found in section 16

This instruction works like a timer controlled switch. The following code is executed once about every second to set new weather conditions. You can test this with 3D objects.
The programm code that defines the lift must follow imediately this instruction and must end with Return. :Label points to an instruction where to continue, after the lift is created or if the switch is not active. This is usually the end of an Area() block.

This is the instruction to change the weather conditions. In the moment only thermal lift and lift by deflected air are known. Thermal lift only works if the sun is shining. Lift produced by deflected air only works if surface wind is enabled in the weather menu and the wind direction is similar to the "dir" parameters. The strength of the lift depends on the wind speed, wind direction and the factor (of lift ?). Depending on the wind speed (10..40 kts) the lift factor is typicaly from 6000 to 1000.
